As it's reproductible, if it was a memory issue I think it would have
already found it.
It seems to be related to ioapics, so maybe a chipset issue. But I still
strongly suspect a hardware issue, or maybe something that changed in
BIOS. You may be able to get it running again by disabling both ACPI 
and ioapics at xen and NetBSD levels:
kernel=xen.gz ... acpi=off noapic
module=netbsd ... -c
disable acpi
disable ioapic
quit
