Which kernel version are you using? Version 2.6.26-20 in
stable-proposed-updates fixes a crash bug in xen_spin_wait(), though I
don't think that accounts for all of the crashes you're seeing.

Unix is many things to many people,
but it's never been everything to anybody.

linux-image-2.6.26-2-xen-686 2.6.26-19lenny2

along with

xen-linux-system-2.6.26-2-xen-686 2.6.26-19lenny2

I can give the SPU kernel a try, wouldn't hurt.

Sadly, that wasn't a magic bullet, two machines went down last night
(both nodes of a fail-over cluster too, ouch). I was only able to
capture the console output of one of them. This one doesn't seem to
mention iret exceptions:
