Yes - it causes a double fault in debug builds of Xen.
In non-debug builds, Xen will survive, but the underlying cause is that
interrupts can erroneously stack with lower priority on top of higher
priority.
The patches have been Reviewed-by Tim, and are currently in XenServer
trunk having a good trashing across all our hardware.
