I'll have to decode the backtrace a bit, but I would guess most likely is
some memory got corrupted along the way, which would be rather nasty. I
already need to follow up on a report of apparent memory corruption in a
domU userspace (testing with the 'memtester' utility), so with a bit of luck
they could be maifestations of the same bug.
