No further information sorry. This was found by the automated test system.
Full logs are available from
http://logs.test-lab.xenproject.org/osstest/logs/104131/test-amd64-i386-xl-qemuu-debianhvm-amd64/
but I doubt any of them will help in diagnosing the issue any further.

It happened during domain shutdown. It might be an edge case
interaction with qemu-raised interrupts via hypercall?
