Ubuntu Installation :: Make Kernel Using Kernelcheck And 200 Lines Patch
Mar 8, 2011
I'm trying to make a 2.6.37.3 kernel using kernelcheck. I have custom compiled two previous kernels for maverick alone, so my .config it will load is optimized as I built with the localmodconfig option, and I have been using the 200 lines patch on my 2.6.35 kernels. I want to find the patch file that works on the 2.6.37 kernel for the 200 lines patch so I can optimize my speed, but the patch i found galbraith-patch is only for 2.6.36.

I am thinking about compiling a custom kernel with Kernelcheck. I would like to know if I do compile my kernel will future kernel updates from Canonical replace my custom kernel? Please explain this in simple terms. This would be my first time compiling a kernel.

there is an issue with the way the Linux Kernel addresses memory by default and the graphic drivers for my Asus G1Sn. I have a patch that I had compiled against a custom kernel for 2.6.27.xx how ever it does not work with the latest kernel in Fedora 11. It is beyond me to rewrite the patch to work with a different kernel.

I just want to upgrade my Slackware 13.1 kernel (2.6.33.4) to the latest stable kernel from kernel.org (2.6.38.2). I have never done anything like this and I am a Linux newbie, so I would appreciate a "Kernel Patching for Dummies" version if possible. I did do a search on this forum and most of what I read was over my head. I found an FAQ on kernelnewbies.org on "How To Apply A Patch" but when I attempted what they suggested, it said it couldn't find the file to patch at line 5 and asked me which file to patch. So I CTRL-Z'd out of there and came here. Here's what I tried:

This morning I ran the automatic upgrade provided on the repositories, updating my kernel from 2.6.38-8 to 2.6.38-10.Unfortunately, upon reboot I discovered that a series of patches I'd applied in order to get my wireless card on my desktop working had been undone (see I had to run a modified version of the instruction set in order to get my wireless back on.My question: is there a way to trigger this every time the kernel upgrades? I'd hate to have to run this cumbersome set of commands manually every time.

I just got the new kernel update (2.6.32-24-generic, according to "uname -r"), and I went to restart my computer as the system requested. When I selected the new kernel from the boot menu, the Ubuntu splash screen came up, and then it did this subtle alternating shades of purple horizontal line thing. Then a vertical line appeared towards the right of the screen, and then everything faded into this cloudy, bright white splotchy...thing.
The keyboard was still responsive, and hitting ctrl+alt+delete restarted the machine, at which point I tried to replicate the problem, but everything loaded normally this time. My questions are: What the heck happened? Why? Is it dangerous? Why or why not? My machine is a Dell Inspiron 1501, 2 GB RAM, 120 GB hard drive, ATI integrated graphics, AMD 64 Anthlon X2 processor. I'm dual booting with Windows 7 as I learn Linux.

I am trying to compile the iscsi-target software SCST. It wants me to apply a patch to my Linux kernel in order to allow for certain performance gains. The problem is I still new to Linux development. Where do I begin? How do I apply the patch? Do I need to recompile the kernel? I am running Ubuntu 10.04.3 amd64
Kernel version 2.6.32-28-server

I did the latest patch/update to lucid this morning and it would appear that my Volume control has gone missing from the task bar. There doesn't seem to be a volume control in Applications > Sounds & Video either. I am sure this has to do with the patch upgrade that I installed as everything was working fine before. For that matter, I had no system sounds either and it took a power off reboot for that to come back. My Music program (atunes) is not working properly either and keeps locking up. How do I reverse this patch or get my system back to a functional state?

Very cool news on a small patch that apparently works wonders with the linux scheduler. Click here to see Phoronix testing of new 200 line Linux Kernel Patch shows it does wonders for performance

Ok here's the problem : I tried to patch the kernel of my Debian server with GrSecurity but when I rebooted I couldn't SSH the server anymore, but my host has a rescue system that lets me SSH the server so I can fix things.
So maybe the kernel patching failed, maybe it's a only a problem with Grub.
I don't really know what to do to fix this. If I messed up the kernel what can I do ? Can I just fix the problem by modifying the grub entries to only boot on the old kernel (I don't even know if it's here anymore, I'm quite the n00b) ?
Well for now I'll just try to mount the partitions (won't let me do "mount: can't find /dev/sda1 in /etc/fstab or /etc/mtab" )
edit : to be clearer my main question is : how can I determine if it's because the kernel is messed up or because the system wouldn't boot properly ?
edit 2 : is there a way to create a log of what happens at boot so I can have an idea about what's wrong ?

IMO it really is the big thing! The patch being talked about is designed to automatically create task groups per TTY in an effort to improve the desktop interactivity under system strain. Mike Galbraith wrote the patch, which is currently in its third version in recent weeks, after Linus Torvalds inspired this idea. In its third form, this patch only adds 224 lines of code to the kernel's scheduler while stripping away nine lines of code, thus only 233 lines of code are in play. Tests done by Mike show the maximum latency dropping by over ten times and the average latency of the desktop by about 60 times.

I;m installing RTAI and I get this message. I can't seem to find the solution, because I really don't know exactly what the main problem is. There are a list of error,s and warnings that I 'm not sure from where should I tackle the problem: Here is what I get when I boot my 2.6.31.8 kernel with GRUB. (I used the RTAI x86 compatible patch):

I'm having problems to install SCST in Fedora 11.I'm not able to apply the kernel patch because there isn't a file called drivers/scsi/scsi_lib.c in the /usr/src/kernels/2.6.29.4-167.fc11.i868.PAE.Does anybody have an idea on how to proceed?

Got a few multiuser systems for which scheduling an occasional reboot is a major PITA. Wondering if the ksplice solution is as painless as it sounds or there are tradeoffs.

I was going through init/calibrate.c.url
I am not clear with use of + sign before function names. If any one here is aware of this syntax let me know.
They have used + and - signs before some lines I am not sure of what they are?

When a real kernel version is upgraded, like say 2.6.32 to 2.6.38, the old kernel is left intact and is ready to be used in case of a problem with a new one, but when only a debian patch version is updated, like 2.6.32-30 to 2.6.32-35, the old kernel is replaced with a new one. More then this, aptitude shows that older version is not in repository either, so how do you supposed to revert back? Well, i did found -30 in apt cache when i got hit by a nasty regression in -35 yesterday, but what if i had cleaned apt cache?

[URL]... Anyone got this going on slackware? I've a single cpu and twincore here and the videos of the original patch were impressive. I tried it and I don't have /sys/fs/cgroup anything. So I added the cgroup scheduler in 2.6.35, but no dice. Do I have to go to git or 2.6.37??

The file /lib/modules/2.6.33.7-pclos6.bfs/source/include/linux/autoconf.h does not exist. Please install the package with full kernel sources for your distribution or use --with-kernel=dir option to specify another directory with kernel sources (default is /lib/modules/2.6.33.7-pclos6.bfs/source). How can I direct it to install with the 'full kernel sources' ?
