what's going on in this trace?

[Chris Pascoe]

Hi,

I was wondering if you could make any sense of the following trace, taken
after the machine crashed (hangs at checking root filesystem, then
eventually runs out of memory and panics 2.4.9-13XFS_PR1 enterprise
kernel, with aacraid driver which has intermittent problems).  In
particular, what's happened after (before?) the interrupt handler - any
way to find out, or does it look like something's walked over the stack?

(extract from ps).
