OK. I've been able to recreate the crash. I was running LTP on both Dom0 and
DomU at the same time. I monitored what was running at time of crash, and both
domains were running the growfiles tests; DomU was running gf16 and Dom0 was
running gf15 when Dom0 finally crashed. Before the crash, however, a number of
oops were displayed on the console, same as in my original report. 

I have a similar machine loaded with FC4 where I ran LTP on both Dom0 and DomU,
and the problem did not occur.

Here's the complete serial console output:
