Are you running an SMP or UP domain? I found I could get hangs very
easily with UP (but I need confirm it isn't a result of some other
very experimental patches).
The hang occurs with both SMP and UP compiled pv_ops kernels. SMP
kernels are still slightly responsive after the hang occurs, which
makes me think only one proc gets stuck at a time, not the entire kernel.
The patch I posted yesterday - "xen: fix RMW when unmasking events" -
should definitively fix the hanging-under-load bugs (I hope).

Nice work!
