acpi=off needs to be specified on the xen command line rather than
kernel's. Might be worth trying that.

Running without acpi isn't ideal, though.

To debug the xen issue, use a DEBUG=y build of xen then you can access
the xen debug console on either serial or console. That should enable
you to get a RIP out to find where its looping.
