Problem Description:
I have a smp server which crashes frequently ( once every few days).
At first i thought it must be hardware-related but i couldn't find anything.
Finally, i learned that the switching off smp-support cures the problems.
I then tried a few different kernel-verions (they all crash) but the 2.5.60
kernel logs something which may be useful.
This is in the logs, just before it crashes:

Etc. etc.
It reproduces. I have seen the exact same loggings at two different crashes.
Steps to reproduce:
Nothing special. Just boot & wait.
