Kernel is crashing all the time.

Hi. I have major problems with my kernel... It crashes so often.
Sometimes it runs OK for 10 days, sometimes it can crash after 2 days...

>> I noticed that when I tried to do 'emerge -uD world', kernel crashed after a while... I rebooted and tried to do it second time...and it crashed again. <<

I also printed out the output for /var/log/kern.log... here it is:
http://elu.dyn.ee/kernel-crash (if the link won't work, let me know... if my kernel crashes, I need to reboot and updating IP takes time)
I can't figure out what's the problem with that... I also tried to update kernel... currently I'm running '2.6.11-gentoo-r6' and it crashes... few older versions also crashed.

Gentoo and kernel works very fine on my other amd64... but why it won't run perfectly under my server machine which has: AMD Athlon(tm) XP 1800+, 2x256 mb ram(dual).
May that problem what I described before, between >> <<, be involved with memory?
Any help is appreciated... I need to get that machine stable.
Big thanks.

Does it work with a different / older version of gentoo-sources?
Does it work with a different kernel patchset?
Have you checked your RAM for errors?

Few months ago I checked... memory looked OK... and no, it also crashed with older version of sources....thatswhy I tried upgrading.

Then the first thing to do would be to try vanilla-sources. gentoo-sources aren't really appropiate for a server anyway, since they're geared more towards a desktop system. vanilla-sources is usually best for a server, or hardened-sources if you want to build a hardened system.

Ok, I try vanilla...but everything else is same? I compile and conf it same way? And may I use my existing .config file?

I suggest you don't use the existing .config - create it from scratch using menuconfig. gentoo-sources contains too many different symbols for make oldconfig to work reliably, and just copying over the config is a very bad idea.

What You think of 'genkernel' ? I haven't used it yet but I heard that making conf file is much easier with that(it guesses your hardware etc)... but I guess that better is still to make it all by hand?
Like I have always done:
make menuconfig, make, make modules_install

I never used genkernel...
But using genkernel for a server isn't a very bright idea, IM(NS)HO. Frame buffers, sound support, graphics and the like have no place on a server.

Actually sound support is needed.. I have radio card and I want it to record 1 show every week and then place it under webserver some folder.
But Ok I'll do it by hand.

My file server is crashing also. It will not even fully boot now. Been having problems so went back to stable nvidia, updated xorg and it ran over night but now

I've been reading a lot of threads about lockups. Some about KDE or X but I'm not even in X and it crashes. 2.6.11-r6 gentoo-sources

Booted now but for how long

X on a server?
Ew!

Replaced the memory. So far it seems to be going well

Guess I'll find out how good the lifetime warranty on Crucial memory is.

fuSEboX,
Sounds like a hardware problem. Try running memtest86.

CarlUman,
Way to hijack a thread. :evil:

Temperature. If it happens under load your cpu could be overheating. Check your sensors in your OS of choice and see what temp your cpu is under load. The heatsinks often get furry and this makes them ineffectual - blow them out with a hairdryer on cold.

I can't belive that it's because of temp. Under heavy load CPU temp is about 56... And it has been even 60 but still worked fine. But now it crashes even if the temp haven't raised much...(in the beginning of some compilation or whatever)

Have you considered the power supply? I know its expensive to buy a new powersupply (especially a good one) but if you have the experience I'd say try swapping it out with a more powerful one and see if it is still unstable. I had an xp palamino 1800 machine with a crappy power supply that'd even change the rpm of the cpu fan (I could tell just by pitch) depending on load (cause it can't stablize the voltage on all the lines), and it'd crash during any rigourous computation regardless of temps. Replaced it with a highly energy efficient fortron and it runs great now. (Might be considered a worthwhile investment if the server box is running 24/7)
