2.4.18-xfs (xfs related?) oops report

FYI-

I'm running a disk server off of three 3Ware RAID cards, set up as three separate drives. Each runs XFS. Under high load, the machine hard locks and I can't do anything with it. The past time, it was nice enough to leave a pair of oopses in the log for me, attached below.

I've also seen corruption in that five 200MB files I was working on have been truncated to length zero.

Machine is a 2x733Mhz PIII with 768M of good ram (tested; it ran memtest86 for 24 hours with no problems).

Kernel is 2.4.18 vanilla with XFS 1.1.0 patch applied in an attempt to fix the problem (lockups also seen on an earlier version).

Debian linux, GCC 2.95.4.

Thanks
-Eric
