Oops on 2.2.0

I have run across an Oops on 2.2.0. It seems to occur under random
conditions, after various lengths of uptime (ranging from 5 minutes to 3
hours so far). A colleague wrote the message down, so there may be mistakes
in the translation, but i don't think so.

The system is a Dual Pentium-2 400, 256 MB, EATA-DMA RAID controller on a
Tyan 1892D board (I am pretty sure that is all correct). It has been
running great under 2.0.3x.

I am not sure how to proceed, or what I can do to help further. They system
is once again under 2.0.35

here is my oops text, followed by my ksymoops output:
