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.
