I have Debian Linux SQUEEZE version 2.6.32-3-686 (Debian 2.6.32-9)
(gcc version 4.3.4 (Debian 4.3.4-8) ) #1 SMP Thu Feb 25 06:14:20 UTC
2010 custimized on my own cd.
I had also the made the same cd on debian lenny version and there wasn't any problem at all.
In Squeeze I've tested on a few pc's and had a same problem after few reboots system hangs up.Here is how to reproduce problem:
I've noticed that sometimes (very randomly after reboot) when i
log into console after typing password and confirm it , sometimes I must
wait a few seconds to get the acces to console which is obviously
abnormal, then when I look into var/log/kern.log file it gives a bug
info (every time the same on different pc's) but i dont'know were to
search the problem. Also after doing the reboot command when there is an
error in kern.log file the systems stops few services and hangs up and
only hard reset can help.Here is tail of the kern.log file:

Aftrer many days spended on finding solution i've give up. Any help would be appreciated .
Ps. Last test was to unload all nvidia drivers from customized cd
and testing on intel graphics card. So far looks good but what about
nvidia gpu ?
