Steve,

I've followed Keith's suggestions and added

        append="kdb=on,nmi_watchdog=2"

to lilo.conf and built a new kernel to go with it (kdb enabled).  I've run
tests this morning and get either : good iozone run, or lockup/hang
(3).  There were no more panics.  I'll try more tests after lunch, but
if nobody's got any more ideas, I'll throw in the towel and check back
in a couple weeks (maybe this bug will get fixed by then).

The xfs code is what I downloaded yesterday after lunch and my kernel is
2.4.4-xfs.
