Friend: "You are good with computers right?"
Me: "Yes...."
Friend: "Can you put an eye on my computer? Mint crash at every startup"
Me: (Oh Linux! For this time ok) "Yeah, show me"
My friend open the pc...
Pc: "KERNEL PAAAAANIC!"
Me: ".... WTF!?"
Friend: "Can you repair this?"
Me: (shit.)
That was a long day...
(My friend closed the lid without the drivers and then the pc from the standby did not wake up correctly)6 -
Did the Kali repos get pwned? Updated to kernel 5.3.0 and rebooted to this. File is 8 bytes, contains just "fuck you".

The Linux kernel team working on the Intel bug considered naming their fix:
Forcefully Unmap Complete Kernel With Interrupt Trampolines, aka FUCKWIT.
😂😂😂1 -
So, none other than the father of our beloved Linux kernel - Linus Torvalds, just totally put an antivax guy down in the public kernel mailing list.
I think I love Linus even more now. He may not be a people person, but he sure does know how to totally rip people into shreds lol.

--- Linux wants some hugs, and everyone gives a hug about it! ---
After the CoC controversy revolving around the Linux Kernel project, a change introduced by the CoC is being put into practice:
Jarkko Sakkinen, from Intel, started replacing words comments containing "fuck" with their "hug" variant. This means comments such as
/* master list of VME vectors -- don't fuck with this */
might look a bit different in the future:
/* master list of VME vectors -- don't hug with this */
People that oppose this change criticize that the comments will make much less sense to people that aren't fluent in English yet. They also do not like the redundant censoring - the actual meaning is still implied, just no longer included as clear text. It might also cause misunderstandings to people working with the code.
Those supporting this change, aside from jokingly mentioning that this change will save one character per f-word comment, note that this can give the Linux Kernel project a more positive feeling with anyone who works with the code, with "fuck" mostly associated with bad feelings, while "hug" is indeed mostly going to call positive feelings in our subconscious minds.
Who doesn't like a good hug? :)
What is your opinion on this rather controversial topic? Feel free to let us know in the comments, as we are very interested in your stances and arguments on this!

How to from hapiness 100 to 0 in seven simple steps:
1. Buy a new 2018 gaming laptop..
2. Install Linux on it for work..
3. Figure out your touchpad is not supported even by latest kernel rc..
4. Spend four days going through forums, bugzillas and overflows while messing around with recompiling kernel, drivers, configs and 3rd party libraries..
5. Lie down and pray someone will add support for your device in kernel in near future..
6. Try not to cry..
7. Cry, cry a lot..10 -

Everything good except ethernet not working.
3 hours wasted, updated the kernel, three network managers changed, realised that the ethernet wire was loose at the modem end.

Buses in Slovakia uses RPI 2 for they TVs apparently they don't manage it so good if they got Kernel panic.
The RPI loses power when bus turns off.
That's what you got bitches for shuting down RPI the dirty way(disconnecting the power source).

The new spider man game made me laugh.
He is "hacking" into some building and says this:
"Lets take a look how good your security is."
"You missed the latest kernel patch."
Still its not really the proper way but the game actually included something what is actually really possible.
Sadly i doubt he could remember and actually know the latest patch in kernel LOL.13 -
Compiling a compiler right now. Doing that just to build kernel with latest compiler because gcc9 is more optimized for zen finally.
If you are wondering. Yes its Haxk20.9 -

OK. I may have the position on devRant as the "Android Guy" or just Haxk20. Yeah sure i ported oreo to a 2012 device that had android 6.0 previusly and 7.0 never even touched the device before. Pie is 95% done. If this build comes in as success then its 98% done.(Fucking lineage-sdk error (Cant seem to find any solution to it hopefully make clean will fix it)). Impressive ? No its not. Guys have done much much more work on older devices and with full support. Yeah sure they are doing it for long time and im just begginer in this since im only porting android for 2 years. But im gonna go to the new territory. Android kernel porting. (No im still going to be porting android. Its just that i need newer kernel)
Does it sound crazy ?
No ? well it fucking is.
Device has 3.0.101 kernel. Hopefully i can bring 3.4 to this babby so i can run some new stuff on it that i coudlnt before since it threw error as "Kernel too old" Yeah i coudlnt chroot into Linux system on that phone because the damn kernel is just so old.
Yeah i didnt even know that error actually existed ffs.
Best part at this ?
I dont have a fucking clue how to do this shit.
So yeah this is going to be fucking fun.13 -
Me, hacking the sunxi kernel to access gpio on my orange pi:
My friend: "oh, a raspberry, are you using python for that?"
Me, looking up from opcode dump: "you can use python for this?"3 -
So apparently this guy has the infrastructure for the Linux kernel mailinglist archive sitting under his desk.
And then there was a power outage.
While he's on vacation.
Now, someone has to physically go there to enter a LUKS passphrase to let the system boot again... 🤔😂😂😂
Sometimes I don't understand people.

Has anyone looked at the linux kernel 1.0?
I am amazed with this! And the comments are priceless
e.g:
tcp.c
/* I hope this returns what I want. */
return(~d+1);
buffer.c
* 14.02.92: changed it to sync dirty buffers a bit: better performance
* when the filesystem starts to get full of dirty blocks (I hope).
*/
So cool!!!!3 -
Last night I compiled my first kernel module!
I'm not talking about a ./configure; make; sudo make install kind of thing...
I wrote, compiled, loaded the module and saw my silly "Hello World!" message on dmesg!
Using some previous experience on embedded I fired up qemu with a fresh buildroot image and the kernel image I just made, thus I can now test and debug without doing kernel changes to my workstation!
So yeah, I'm a little excited :-D5 -
It's gotta be the Linux kernel.
It's so good at managing base resources on all platforms that it allows hundreds of thousands of hipsta-ass devs to write shitty code and still get decent speed.1 -
Wohooooo. All the bugs i reported got fixed in latest drm patches. Awesome.
Running linux-next and its bugless.
Lets enjoy the bugless experience on totally latest kernel thats even possible until new bugs appears.4 -
To me, it seems like the rise of distributed systems like mesos / kubernetes combined with Docker require you to be master sysadmin, veteran kernel hacker and a part time c developer ALL AT ONCE if you really want to shave off time from debugging/ performance tuning sessions. Anyone wish they paid more attention in class ? Lol.

Android 8.1 on Nypon ?
They said i was crazy.
Im not crazy i just want it to run 8.1 no matter what.
Bootanim reached. Android part mostly done. NOW just binder kernel shit and im done.
To be honest i expected just kernel screen and reboot. Well it got bootanim and then crash due to missing binder stuff in kernel.
Now this is going to work.9 -
->buying fake arduino from ebay.
->have to install separate drivers, because the manufacturer uses a cheap usb to serial chip.
-> driver page is all in chineese, only the download button is in english
-> installed the driver(at this point there was no going back)
-> rebooted
-> instand kereal panic

I compile mesa from git i said.
Its easy they said.
I compile LLVM from git i said.
Thats easy too they sad.
Too easy ? i said
Yeah they said.
I compile kernel on daily basis from git and thats my only kernel on my daily machine, I compile Wayland, xf86-video-amgpu, gnome-shell, mutter, libdrm, gtk4 and Xorg (IDK why even tho i dont use it) at least twice a week i said.
You are crazy we fucking give up they said.5 -
Wow compiling kernel for linux tablet on arch linux machine booted with ubuntu 16.04 LTS I will be really suprised if it will build kernel and will work

I'm the only one working on this anymore and every toolchain supporting the system (remember, we're using an ARM9 [initial strap CPU] AND an ARM11 (give or take an ARM7 slaved to the ARM9 that we don't have support for yet), all in tandem, and the only toolchain that remotely works is for ARM6 for some reason) hates the Linux kernel. Current goals: SD R/W support (currently RO), X, GNUTools, maybe a better fucking softkey driver (i'll have to find whoever made this one and fucking beat him), and a working joy2mouse/touch2mouse driver. Oh, and figure out if Swap would work either with the New 2DS/3DS' Bonus Drive (unused 64MB partition on NAND) without killing the NAND as the SD access is max. 1.2 MB/s read/write speed or so, which isn't fast enough for swap AND other things.
Currently working:
Busybox
Read-only SD support
Weston (term only, can't click)
Standard 3DS/Standard 2DS/New 3DS (Models before 2017, the non-foldables, rebranded standard 2DSes) features only, not yet New 3DS/New 2DS-enhanced
Currently failing final compile because toolchain:
Preliminary custom R/W SD support

Well finally ubuntu 17.04 fixed lot of fucking bugs and kernel 4.9 maybe will add audio so yeah maybe finally functional tablet yayyy

Our new hired (promoted intern) just installed Ubuntu on his new machine.
Now we are the only ones using Linux at work.
He was having trouble with a flickering bug on kernel 4.4.0 and I just told him to apt upgrade that it would solve it..
And he was like: oh.. Can you update the kernel?
That's gonna be a long month...hope he learns this faster than git7 -

And I cannot because of kernel version and I have it all ported now I fucking need to update from 3.0.101 kernel to 3.4 shiiiiiiiiiiiiiiiiit.
Wish me luck.
Ahhhhhhhh fuuuuuuuuuck.2 -
New 4.12rc1 kernel out let's compile
After half hour (ccache)
Fuckkkkk need to reinstall old kernel cause of error fail boot
Now downloading again 4.12rc1 hopefully it will work this time -
What a new years start..
"Kernel memory leaking Intel processor design flaw forces Linux, Windows redesign"
"Crucially, these updates to both Linux and Windows will incur a performance hit on Intel products. The effects are still being benchmarked, however we're looking at a ballpark figure of five to 30 per cent slow down"
"It is understood the bug is present in modern Intel processors produced in the past decade. It allows normal user programs – from database applications to JavaScript in web browsers – to discern to some extent the layout or contents of protected kernel memory areas."
"The fix is to separate the kernel's memory completely from user processes using what's called Kernel Page Table Isolation, or KPTI. At one point, Forcefully Unmap Complete Kernel With Interrupt Trampolines, aka FUCKWIT, was mulled by the Linux kernel team, giving you an idea of how annoying this has been for the developers."
>How can this security hole be abused?
"At worst, the hole could be abused by programs and logged-in users to read the contents of the kernel's memory."

OK i have 2 more free days.
What would normal person do ?
Go out and have nice time with friends or watch TV or some other non interesting bullshit.
What will i do ?
I will spend the entire 2 days building 4.17-rc2 kernel and fixing kernel panics since as i know it everything will fuck up.
Thats what i call nice spend 2 days !!!!1 -

Whoever said that Linux "just works" obviously never had to use 5GHz wi-fi. I can't even 'make' the kernel module. And last official driver only supports kernel <=3.12. I guess I will have to use Windows ):13

Linus Torvalds on C++
“C++ leads to really really bad design choices. You invariably start using
the nice library features of the language like STL and Boost and other total and utter crap, that may help you program, but causes:
- infinite amounts of pain when they don't work (and anybody who tells me
that STL and especially Boost are stable and portable is just so full of BS that it's not even funny)
- inefficient abstracted programming models where two years down the road you notice that some abstraction wasn't very efficient, but now all your code depends on all the nice object models around it, and you cannot fix it without rewriting your app.”

Reporting all the fucking bugs that i get on Acer Nitro 5 so its well supported on linux and new users will not have an issue.
And in even better news im starting to understand the code slightly so i might even propose Kernel patch this year.
It isnt the first time i heard "Become a fucking Kernel Dev already" on devRant.11 -

Fuck it.
If Torvalds completely steps down and shit starts to absolutely suck in our beloved kernel then it might be high time to start paying close attention to Minix or Hurd :P options peeps. Options are good.5 -
After ages of waiting for it too install, i finally managed to update my kernel to the latest version.

AMD freesync is beign merged into 4.21 in a while. Mesa patches will be in when kernel support is in place.
-
OK OK its time. Updating mesa to latest git commit. Upgrading kernel to latest commit.
Why ?
First im crazy and i love to run latest shit.
And second i finally have FreeSync !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Oh yeah. You know what that means. Time for some games.
Uhmm i mean. One game only is good enough to test freesync on it. And thats Elite Dangerous and then i might test others.
Oh also other crazy stuff is in the latest kernel so yeah.8 -
You know that, there is an app which stops the windows automatic updates, it is called linux kernel. But it goes beyond that, I have fixed mac os issues with that as well. Love it3

I fucking hate old android kernel.
Its fucking terrible to port new android Oreo to 2012 device while having kernel 3.0.101 (Yeah seriusly).
I need about 10 patches for only SElinux to be version 30 so it can even boot.
AHHHHHHHHHHH2 -
I just compiled my own kernel. It took me such a long time [because i'm a crackpot or because i'm german] that i'm not even a hint proud3
-
I just have my Rpi set up to compile latest kernel from master every day. And i have my arch notebook set up to download the kernel from server and check the package name and compare and then if its newer then install it. Poor little Rpi. Still cant figure out how to build X86 on Rpi tho. Probably wont use Rpi for it and will just do it on server and host it there too.2

Tl; dr: Linux on Ryzen is a pain at the moment.
Now for the long part: Our student council got new computers because the old ones where slow as hell. As one of the admins, the others and I together decided that ryzen would be a good option, because they are not that expensive and we wouldn't have to buy gpus. (Wrong decision it turns out.) We settled on the ryzen 3 2200G and bought three systems to replace the old ones.
We meet Saturday morning and build the systems. All was fine and we were happy. The we tried to install ubuntu via preseeded netboot, which seemed to work fine at first. Then we started having weird screen issues and couldn't proceed with the installation. (See image) we then grumpily decided to just install them all one by one, flashed two usbs and started installing. On two systems the installation worked and we installed our packages, we weren't so lucky with the third one. It would crash on us all the time, even in bios. While that was going on we tried to set the other two up, turns out those two were also crashing but not as frequent as the other one. So we start to google and find people saying that kernel 4.19 kinda fixes it. We install it on the two working machines and the crashes get less frequent but are still there. At that point it was midnight and we went home.
Sunday morning: we reseated the cpu on the third system and it seems to be better now (it installed on the second try) and we were able to change the kernel. Yay. Now all three are in a state where they will sometimes randomly reset. :/ and we don't know what to try anymore.... Any suggestions?

1) Hike on mount everest
2) Job that I'll love
3) Go on road trip with my friends
4) Renovate home
5) Create my own operating system(not based on Linux kernel!)

Was at a Saturn (tech store) a while ago, just in the area and browsing a bit, and then this: (see image, thanks C0D4)
This sort of shit happens all the time around here.
There was also my local Karlchens Backstube (bakery and café) where the drive-thru display had a green screen of death; I don't know why they used an insider build of windows. Or windows in general for a fucking DISPLAY SIGN. A FUCKING DISPLAY SIGN WITH JUST A STATIC IMAGE DISPLAYED.

So it seems rc builds arent bleeding edge enough. Well how about linux-next now ?
Ouuuuuuu yeah. 4.20 is kind of broken for me and i hope that 5.0 will fix it.
Using linux for over 5 years now and i didnt even know what linux-next is and it was unknown to me . Sure i heard about it but now im doing with it something. Exciting as fuck. All the totally latest fucking stuff.2 -
Who would thought that backporting 8.1 commits in kernel would be such a pain.
Thankfully we have cherry pick. -
Users running Linux on laptops with Intel processors should avoid Linux Kernel 5.19.12 due to an error that might physically harm the display. Fortunately, kernel 5.19.13 has already fixed the issue. Versions 6.0 and 6.1 have also begun rolling out with many significant changes.4

I was finishing compiling the linux kernel in tty mode for a school project in the subway cuz the class was over and it was not finished. A guy came to me and said : I used to do that, but on a Mac. Then he left. I was like : wtf do you think I'm doing? You don't compile the linux kernel on a fucking Mac. And why would you mention it was a Mac anyway?I guess he just did ls -al on his Mac in tty.6
-
I really wanna dive into low level stuff (kernel modules and shit) but I'm genuinely scared of this stuff, very very steep learning curve. I'm pretty sure I'll just spend 4 hours cluelessly trying to make something work. One day I'll find the balls to learn it tho.4

Well this is crazy. My laptop builds kernel in 50 minutes. Or around there. Thats on M.2 SSD so its faster to do.
Now my server which currently runs on USB (USB2 even). Yes the OS is installed on USB and it compiles the kernel in 10 minutes on USB2.
Can you imagine how fast it will be on fucking SSD ?
Yeah...
Really fast.
Im happy with my choice.
Sure the sound but TBH i got used to it already.16 -

The name 'tasklet' is misleading: they have nothing to do with 'tasks', and probably more to do with some bad vodka Alexey Kuznetsov had at the time.

After 8 hours of carefully installing Gentoo in my laptop I ended up with a... Completely unusable OS. Guess I'll try again tomorrow, apparently I didn't set up the kernel with the appropriate drivers.2
-
Yaaay for Debian 10 (Buster) coming out next month. Should finally (hopefully) fix my laptop touchpad issues 🙌
Also, really looking forward to its other features aswel, newer GNOME and kernel 🙂8 -
is it fair to say linux is the most popular operating system kernel?
i mean, it powers android, the most popular mobile os, chrome os, nearly all servers, raspberry pi’s, embedded devices and linux desktop operating systems. it has the be the most popular kernel, right?7 -
Interesting...
AMD wip 4.21 branch which is based on latest rc3 boots up totally fine and works flawesly actually. Maybe only issue is wayland black screen when switching GPU but thats OK tbh.
On the other hand the latest rc3 from git from Linus doesnt boot correctly for some fucking reson and starts a start job for 2 services that never fucking end. So now tell me WTF is wrong ????????????????? becasue i have no fucking clue what so ever. Config is OK because i compiled AMD kernel with it and it worked OK but with linus kernel it hangs on that start job. I will try one last fucking thing and that is to use PKGBUILD from AMD and just replace the kernel source with linus one. If that boots correctly then oh shit we have a fucking issue because when 4.20 comes out and Arch will use that fucking PKGBUILD then i woudlnt be able to boot whatever i fucking do.
But its still crazy that AMD kernel works OK.
And its supposed to be more unstable then Linus version. FFS !!!!!!!!!!!!!!!!!!!!!!4 -
To Mac fan boys... Suck it. In the time I've had 1 BSOD on Windows 10 I've had 7 kernel panic on Mac is x at work. And the MBP is newer.6

Getting back to the cpp applet I started somewhat recently (Vanilla + Gentoo kernel version checker)...
Me: "debugging c plus plus code"
Dictation: "f***ing c++ code"
...
Well, it's not too far off. -
First I didn't switch to the 4.18 kernel because it breaks thousands of gnome extensions and customization, now newest gnome broke it all too and downgrade caused gnome to just blackscreen, time to re-install12
-
I wish all apps would just stick to the monthly updates in the fashion of Linux kernel, Android, etc. Why the fuck does a mouse driver have to be updated every fucking week? Jesus Christ.3
-
Compiled the linux-4.20 kernel with an allyesconfig (coz, why not ? ). The joy when it compiled.....
Boot the kernel, it says initram too big.2 -
I've been noticing that without any specialization development can become repetitive, as in, a bunch of fancy ways of doing the same CURD operations.
Something that just calls me is low level development, wether it is embedded development (microcontrollers and such) or Linux Kernel and device drivers. I've been polishing my C skills for a while now and started to look into kernel development and uff, is it overwhelming!
I just wanted to see if some of you guys are or had experience in system development and how you got there. Thx!3 -
To those who think the kernel "lacks diversity": http://remword.com/kps_result/...
There are more COMPANIES contributing to the kernel than most github projects have stars. There are more COUNTRIES contributing to the kernel than most software projects have active developers.There are more COMMITS going through the kernel per day than most software projects have in their entire lifetime.9 -
io_uring hardly works and yet was accepted into the mainline Linux Kernel.
Has been two weeks of headaches.2 -
So I was compiling Resurrection Remix, Android 10. And I'm making some commits here and there, and my friend looks over and asks me "so how does this work?" And I briefly explain about device tree, vendor and kernel. So he says "oh okay, so basically it's like copy and paste?"
I've never been so offended in my life 😐3 -

If Tetsuya Nomura was directing the development of the linux-kernel, we wouldn't have got Linux 5 but
Linux IV.20.9 and 4.14 LTS would be 4.14.5 Final ReMix with added features that contradict later kernel-development. -
Anyone else getting a bug with every opengl application on Linux? Gives me an error something like "X error of failed request: badvalue"
Weird- maybe happened in the latest kernel update? I'm using 4.147 -
Why the hell did someone remove the wacom kernel module in android since 4.x? It wasn't hurting any body and instead gave people the ability to connect their wacom tablets to USB OTG compatible devices. As a result we have few apps that have wacom support in play store and shitty reputation that the rotten apple is better for all things media.
And for me it means I have to:
* Figure out a way to root my device
* locate correct version and configuration of currently running kernel.
* set up cross compilation toolchain
* build the kernel module
* transfer it to the device
* insmod it manually
* say a few prayers
.... All I wanted to do was paint 😢 -
Joined Eudyptula Challenge yesterday. Who else is trying to be part in the Linux kernel development or already is ?
-
That moment when the cash point gets restarted, a Linux with kernel 2.6 boots and you wonder why there is a postfix service running...
-
I just wondered... Is it even possible to write unit tests for an OS kernel or a bootloader?
How would you do that?2 -
To make a semi-meaningful (or really any kind of) contribution to the Linux kernel. Like just to leave something useful behind in general.2
-
Xperia P mainline:
UART doesnt work. Fucking bootloader doesnt set the L2 cache and doesnt lock it.
Kernel crashes right after uncompressing.
I had no clue what was wrong since UART doesnt work and i was thinking its just something wrong with the file since Data Abort. But thats kernel crashing before it can segfault or panic and just drops and bootloader tells you something went horribly fucking wrong.
So now i need to port u-boot which is kinda OK considering there is port of it already for the processor. Oh the same UART shit. What a surprise. So i need to get UART working. USB working so i can flash kernel via u-boot and then i can mainline this shit. Just WOW. -
The fact that the latest Linux kernel added support for 32 bit systems to function past 2038 is one of the most baffling things I've ever seen in development history... Not saying it's a bad thing... But.... Why3
-
I need to improve my C skills to become a kernel developer, so that I can do that full-time at some point. And since it would be 100% remote I could live wherever I want and wouldn't need to PAY STUPID AMOUNTS OF RENT JUST TO LIVE IN A """CITY"""1
-
On the kernel/os project I'm working on with @SoldierOfCode.
It's a side project but I *need* to refactor the normal text based functions to vga graphics compatibility.3 -
Mainline XPeria P progress update:
Non booting. No UART. Nothing.
Kernel seems to Data Abort even before uncompressing or whatever.
So far i want to burn it all.5 -
1) A widely used compressing algorithm as my very own invention.
2) Master electrical engineering
3) An universal OS Kernel as my own invention. I will declare war on Linux and Windows -
Wrote a PLSQL exam yesterday.
Had to do it on a sheet of paper instead of using Eclipse (which we normally use in lessons)
My brain :
kernel panic - not syncing
It was the worst exam I’ve ever taken😅4 -
Why did Microsoft lock down TTF files?
https://support.microsoft.com/en-us...
None of their links work anymore.4 -
so RC build are supposed to be more stable then -next right ? I have my doubts at this point. 4.20rcx gives me start job always. Trying -next kernel and what in the world is this. CLEAN boot. didnt test again since yes its -next and while every piece of hardware was working the display cut off and had to reboot. What do i expect from unstable kernel right ? But the fix to this is most likely in -next. If it ofcourse wasnt just a luck that it booted up.1

When updating nuget packages takes longer than cloning, configuring and compiling the Linux kernel...
while(true)
bang(head, table);3 -
I have been building kernel as usually but i just noticed i have been running Arch kernel for the past week or so without noticing. I mean i have noticed 1-2 fps drop in FPS and other stuff but this was just weird. Now on latest git commit again and i feel complete again.4
-
When I see how Telegram is being compiled longer than kernel, cannot go into 4 GB of RAM while the kernel is okay with 3 GB I realize that the world is very broken.1

Was bored and wanted to try to update my old LG nas
With a bit of help from @linux i started on the hell hole.
I'm also streaming it and it will not be done anytime soon so come chat if you want

Fucking OVH had an electrical issue AGAIN!!! it's for second time in the last 5 month. had to reinstall the OS because kernel is fucked. thank god i backed up my data5

Looking forward to the day when I'll be building a custom kernel for my "smart shoes" to speed up terrain detection

Nothing like a fucking kernel corruption after Ubuntu update and restart.
It's so great
Really
My two hard drives now are encrypted and to unlock them the kernel should be intact.
The amount of time it'll take to reconfigure my machine to work is insane.
Also, I had commits in products I'm working that weren't on remote. So fuck me.
Now I have to do a fresh install and hope that I can read my second drive.17 -
Ubuntu has integrated EISA support in kernel...
It's time to find a reliable kernel source that does not support hardware that is dead > 25 years.... Sheesh...25 -
Yeah I mean I love Linux, but a kernel panic just when you want to relax and enjoy a nice programming evening? Really Linux? Come on…3
-
Hey Guys,
What do you think about Windows 10 shipping with a real Linux Kernel? Do you enjoy the love of Microsoft towards Linux? If yes, why?22 -
So I found the reason of kernel panic, my laptop's hdd is fucked, lost all the data. Now using a live usb until I get a replacement. Silver lining is I won't install windows for dual boat and replace elementaryOS with arch linux. I want a proper fight now.1

Worst project: porting SCO Unix on Chorus Microkernel. That was in 1995. Great project BUT after months of efforts finally SCO pulled the plug, a few weeks before we were about to get the kernel to boot ... Aarrgghh

Was running personal laptop on 4.10 kernel (running Manjaro).
Was having problems for some reason with an audio program I'm using and so needed to run some older kernel that is real time for better latency.
Installed that kernel and booted with it.
Attempted to remove kernel 4.10, I don't need it anymore.
Rebooted, some kernel modules aren't loading. Xorg not creating a session.
I have no input working.
Not even wifi.
I can't detect USB devices.
Tried to fix it all night.. going through a ton of forums online...
Finally I give up. I didn't have access to anther computer to get a bootable USB image to. FUCK. IM NOT SMART ENOUFG FOR THIS SHIT.
I have 3 USB drive that I carry around all the time. Why don't I have a live image in one of them?
I went to sleep.
Next day I download Lubuntu (just to boot and backup some stuff before downloading and reinstalling Manjaro).
When I was burning the ISO to the USB, turns out I actually had a bootable Ubuntu on it the whole time.
I feel so stupid.
Last week I don't remember why, but I did sudo chmod 770 /
Which also broke my system.
Took me 3 hours to realize that this was the problem and make it work.
I love Linux. It keeps things interesting..3 -
Can someone explain me how a global discriptor table is implemented in a kernel? My problem is basicly that I want to build a kernel that can run seperate programs in userland. But I don't quite understand how the GDT and LDT should be implemented.1
-
I don't understand how I/O streams work. I mean as a userspace developer i saw the stdin/stdout streams as magical objects that i could read or output infinetely in a continuous way, without caring how much data i write or read (ok, not entirely true because overflows)... But now i'm making an os kernel and i really don't know how i'll implement them..... :(1
-
Just saw that Ubuntu 19.04 extended the live patching option to desktop users and we no longer have to restart the system after a kernel upgrade.
And here we have windows which restarts after every bloody security update.
How come Microsoft is such a big shit that they can't put a feature like this in WIndows. They definitely have the resourses and the people. I think they are just lazy and don't think it's "important enough"11 -

A colleague of mine has built a kernel module that is part of our system. He wrote it for Linux 4.4 but in the meantime our servers got updated to 4.15. The kernel API changed from 4.4 to 4.15 so the module does not build anymore. He said he will update it, but in the mean time I figured it would be easiest to just use 4.4 in the meantime. I downloaded the kernel deb package and installed it. Now, after reboot I can't ssh into the machine any more. I just started this project and I'm already tired of it. Every time I fix something a new issue appears. And I did not even start what I am supposed to do1

So I'm writing this shitty kernel/os/abomination with Soldierofcode and I noticed that, to do essentially anything further than a shell, I should use UEFI.
FUCK I CAN RESTART THE ENTIRE CHING CHONG FUCKING PROJECT3 -
Tmw you realize your new shiny laptop has issues with linux.
Gonna have to do some grub stuff, the shipped kernel doesn't support my skylake gfx :/6 -
Ported the dirtyc0w patch all the way down to kernel 3.2.13, that was fun 😀
Yeah, I've heard of LTS 😛 -
Finally decided to work on my kernel update script a bit (basically I compile the mainline kernel and configure it to slim it down a ton for my laptop, and that gets annoying so I wrote a script to do it for me). As of right now it is functional, it MAY require some babysitting, cause sometimes shit goes wrong, but it hasn't given me any problems the last few times I've run it. But it's also written with Arch in mind (using linux-mainline AUR package), because I use Arch btw. At some point in the future I want to add support for other distros, but I also want to get everything functional on Arch first.
If anyone has any suggestions or anything:

Symantec/Norton users please patch your AV immediately, problem that's listed in CVE-2016-2208, which can help you destroy your kernel.

Updated linux kernel (tried about 4 version) to enable mini display and to use 3 displays and it would be awesome if one of my hw's module would be updated as well with it.
Now after 4 wasted hours it freezes at the login with 3 displays...fml -
Transformed my gaming rig into a dual boot hackintosh since I had a SSD from my previous build laying around. Now the fucking thing boots perfectly fine besides that shitty wifi USB dongle which just reconnects 3-10 times to the wifi and then suddenly causes a kernel panic. Fucking piece of shit 😑
-
what the fuck!! I run an update, it said updating google chrome, I rebooted because of kernel update and now I am searching chrome and it is not there
-
I literally don't understand the purpose of a "higher half kernel"
What does it matter where my kernel is mapped in virtual memory?
"It is traditional and generally good to have your kernel mapped in every user process" what the hell does that even mean??
Mapping my kernel into userspace is something is explicitely don't want to do. Like at all. Ever
And in physical memory it matters even less where it is.
I'm so confused right now3 -
Why are you so slow Kaggle...
(((preparing kernel)))
(((committing)))
I have tons of data to analyze with multiple methods...
sigh...1 -
Using memcpy() instead of copy_to_user() in a kernel module. One could overwrite kernel space memory, by passing a kernel space address as destination address.
-
Why would the great linux devs and the 'C prophets' choose K&R indentation model ahead of Allman's model ? Its saddening that i would have to work with K&R style for my future works !5

While using Spyder the python kernel died(not that rare), so I restarted the kernel and... It kept dying over and over and over again.
So I restart the IDE... can't even connect to the kernel anymore.
#Fast forward an hour
Comodo internet security was blocking stuff.
Ffs, I had given up and I was ready to reinstall the whole damn environment if not Anaconda.
I still love Comodo.1 -
Any fellow Gentoo users here? How much pain did you have to suffer?
Should I upgrade my Gnome version to the newest version while expecting no issues? (am running systemd)
Can I just unmask the Gentoo kernel source package and expect to just compile a 4.14 kernel?
I don't want to break that system because I use it everyday...3 -
"The operating system and kernel in Ubuntu Core are also delivered as snaps, so the entire platform is transactionally upgradeable."

With all the people here using and loving Linux, I wonder how many of you have contributed money to either a distro, drivers or the kernel itself?6
-
Well. Here we go... new version of buildroot, new version of the kernel patches, new version of several packages...

Things will keep going like they are now, only faster, until some Malthusian Event (natural or cyber) drops everything to a few compiled languages, a web stack, a handful of frameworks, and a couple of kernel types.

I thought BFQ (Kernel 4.12) should be faster on good old hdds. In fact, it is. I'm amazed. Well done. Unfortunately my machine freezes randomly every few hours. 🤔

Hey, just need a little advice regarding android kernels.
Does anyone know a simple way to download either pre-compiled or source code of stock kernels delivered with phones?
I flashed one, but have some System UI problems, so I want to go back to stock, but I can't find any download.
I'm running a Samsung Galaxy S6 (zerofltexx).6 -
Linux needs a KBI. That driver recompilation thing when upgrading a minor kernel version is so annoying. Solaris, HP-UX, AIX, BSDs had already solved this in the early 2000s.2

Anybody wanna collaborate?
I am currently developing a (MASM) assembler-only kernel for i386 targets. My goal is to build a kernel that is made for web applications by design.
https://github.com/wittmaxi/maxos
If anybody wants to help me, feel free to shoot me a message on Telegram! I'm also happy to teach you some ASM :)
The project is mostly a fun project anyway, so no big pressure6 -
Funny argument in class today and was curious what you lot thought, cuz Im honestly not sure who was right. student argued false. professor said true.
Question:
(True or False): A preemptive kernel is safe from race conditions on kernel data structures.11 -
Is it possible to install Ubuntu (new versions with updates) on a non pae kernel?
I've tried different distributions Ubuntu, xubuntu, lubuntu but everytime I failed..2 -
Projecting and developing microservices architectures at big companies. Also I hope I'll be contributing the kernel a day

Who the fuck thought it is a good idea to disable i2c_hid module in Linux kernel 5.12 by default?
I compiled the kernel 3 times and was wondering why is my touchpad not working...5 -
Ok so that's my plan, find a kernel with HUGE amout of drivers and , high version.
I built a small os based on linux
-- kernel version 5.0.2 from Plop Linux,
many libraries added 'by hand' -- packages from apts of Debian&Ubuntu, and unpacked packages into system with ArchiveManager,
has GUI but it's called xfree86 ( looks strange when a very old app running on Kernel5 )
So, without compiling, i can make a os.
But i found that Plop didn't compile rtl8188eu module which makes linux support some specific network cards.
I have no professional compiler but a tiny C/Cpp compiler called TinyCC (aka. tcc), but for my pc ( CPU freq = 800MHz ), it seems not possible to compile the module by myself.
And then i downloaded a 5.2 kernel with modules from kernel.ubuntu.com, but when i tried to mount my disk ( part. vfat ), i got some errors like IO charset not found, and then i replaced it with Xanmod kernel but also reported an error said Invalid Arguments, but i checked /proc/filesystems, it supports.
So what can i do? Are there any pre-compiled kernel & modules with 'full common supports'?
I tried kernel 4.4 ( from Ubuntu 16.04 LTS ) just now but the driver crashed when wpa_supplicant tried to initialize the device.7 -
Today I had a look at the Linux kernel on GitHub. There was a commit made by someone else which I tried to comment on. But my comment was not getting added— probably because it is not my PR. Is this a feature or a bug ?10
-
I'm compiling an entire Android build from source. Even with 16 dedicated compilation threads, it's like watching paint dry.
It's nowhere near my early days taking over 24 hours to compile a Linux kernel... But it's still painful. -
! Rant
Updated Linux Kernel to 4.8.3 with pacman - Syu and KDE also updated. After reboot I get the message "Could not start D-Bus, can you call qdbus?"
Any clues? -
When you are frustratingly trying to make your app function properly on android 4.2.2, API level 17, kernel 3.0.31; this sacredly annoying particular device!2
