Steven, as I said before, that option affects both Xen and KVM behaviour. So I want to avoid that as much as possible. I you could please give the test1 kernel a try which "only" does not re-enable interrupts of the guest while doing the hypercall. In my testing this also would not cause the hang and would only be affecting Xen which has the issue first place.
