What hardware is the problem machine? It has an impresively long list of
ACPI table entries. Since the code being executed is the native Linux
code it's surprising that it's having problems. 

Please can you try using a DEBUG=y build of Xen, and then adding
show_guest_stack earlier in the failure path.

Thanks,
Ian
