Subjectpanic on 2.6.20
Date
Hi. Sorry for posting to this list,
but I got this panic with linux
2.6.20
I have also changed the motherboard
of this server and memtest has not
found any error (ram tested for 10
hours)
May anyone tell me if this could
be an hardware problem?

TIA

Linux version 2.6.20 (root@Pleiadi) (gcc version 3.4.6) #1 SMP Mon Feb 5

This this the output from:

dmesg | ksymoops
ksymoops 2.4.11 on i686 2.6.20. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.6.20/ (default)
-m /usr/src/linux/System.map (default)

Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
