BUG: unable to handle kernel NULL pointer dereference - 2.6.25.7

BUG: unable to handle kernel NULL pointer dereference - 2.6.25.7

[Roy Sindre Norangshol]

Hi

Last week I currently found our new server not responding to any of it's 
services,
so I went to data center to check on the server. I figured out that the 
logs had a line printing out that
this was a kernel bug (kernel.log) [1].

I tried upgrading to 2.6.26 release - but server died again on saturday, 
so going to check
logs later today (Monday) to see if it's another kernel bug popping up.

I scp'ed the logs [2] over to one of my other servers so you guys can 
see if there's anything useful there.

The system also runs on raid1 with mdadm and if I dont remember right, 
the hardware should be
an Intel Core2 Quad (Q6600) @ 2.4 GHz, 4GB of memory and motherboard of 
type P35 chipset,
motherboard P35C-DS3 [3] (I think) by Gigabyte. System is running Debian 
Stable with some packages
from backports, and compiled kernel myself from sources fetched from 
ftp.uio.no.

I'll provide more hardware information when I reboot the server, so I 
can run lspci, lshw, dpkg -l to provide
you guys with more information as I guess that would be nice. Anything 
else I should run?

NB: This is my first time posting to the list, and as far I understand, 
there is no need to run
the oops thru ksymoops since I'm running 2.6 branch of the kernel. 
Anyway, I'll gladly try to
send more details - just tell me what todo and I'll give it a try.

NB2: I'll probably fall back to standard Debian kernel (2.6.18 I think) 
(build from sources with my config) until I know what's causing this.

No logs after second crash with 2.6.26 kernel, and nothing useful to 
pickup from screen since it frooze..
Back to 2.6.18 I go..

lshw,lspci and such are available here: http://norrs.no/kroton2/

Hope it is of any use.
