I originally encountered this on testing with xen-unstable changeset
11536:041be3f6b38e from 9/19. Both the dom0 and the guest are running
2.6.16.29. I originally encountered it when running with SMP hvm domains but
the problem also occurs when giving the domain just a single VCPU.
I rebuilt on a changeset from today (11620:ef41783c664a) with debug=y and now
my domain crashes immediately after grub loads. It does this on both a SMP
and UP setup and seems independent of the amount of memory allocated to the
domain. This is what gets dumped to the console:
