Default High CPU usages and sometimes hard crashes in my Debian/Linux.

Hello,

The last few weeks, I noticed my old Linux/Debian box (2.6.30-2) keeps
getting random and rare high CPU due to Xorg and sometimes crashes. My
box, even via SSH2, felt slow. I checked the processes and saw:

I tried to kill startx and Xorg processes, and my box froze (still
pingable, remote SSH2 connection frozen but not connectable, and IRC
connections lost). I have tried recompling the latest stable NVIDIA
(from nvidia.com) driver for GeForce FX 5200 (AGP), redoing my
/etc/X11/xorg.conf with NVIDIA's script help, disabling Compiz, etc.

I checked logs. In /var/log/X11, I saw a bunch of: (EE) NVIDIA(0): Error
recovery failed. (EE) NVIDIA(0): *** Aborting ***
(II) NVIDIA(0): Initialized AGP GART.

This sounds bad? What does that mean? End of dmesg showed these lines:

I posted more complete and other logs at, including sensors -f:
http://pastie.org/774029 ... My old Debian machine specifications can be
found in http://alpha.zimage.com/~ant/antfarm.../computers.txt
(Secondary/Backup Computer section).

Any ideas? I do keep my Debian updated daily with apt-get update and
upgrade commands. I do not recall any recent X changes.

Thank you in advance.


You might have a CPU cooling problem. Here is a link to sys_basher, make
sure you have lm_sensors and the lm_sensors development package installed
before you build it. sys_basher will stress your CPU and RAM, if the
system crashes you'll have an answer. It will also record the CPU and
motherboard temperatures between each test which will give you an idea
about how hot things are getting before the crash happens.

Ooh, nice tool! I downloaded, compiled, and ran it for over 30 minutes.
So far no crashes, no errors, etc. I will keep it running until I need
to go AFK (have to abort). How long are the tests supposed to run? I
didn't see it mentioned in its README.

Every problem I have had hardware wise the last three years has been
solved by taking te machine apart and blowing the crap out of it.

Those temps don't look terrible, try running sys_basher for an hour. Use
the -ho switch
sys_basher -ho 1


Well, my first test ran for an hour. Also, I have seen the crashes happen
during nice temperatures (look at previous posts). I don't think it is a
heat problem.

I just did that a few weeks ago too. I will try again later.
