I have not been able to reproduce the crash *before* I applied the
patch.. I did test with the patch, and I still could not reproduce the
problem which is good :-)
I did manage to get a crash dump when I did get that assert though
(see below)..
It has dom0 and hypervisor ram state and symbols. Is there anything
you would like me to look at to very your assumptions?
Thanks,
MRJ
