And here are a couple more. First I get this traceback with a dom0
enabled kernel not running under xen atthe start of the boot log
BUG: spinlock bad magic on CPU#0, swapper/0 (Not tainted)

Secondly I get this crash when trying to start xen under qemu-kvm.
Something similar is happening when I try to start xen directly, but I
can't do serial logging on this computer so I can't be sure.
