Bruce M Simpson d6dd4af4ac Forcibly disable interrupts, if we find ourselves servicing one when ... the device is suspended or shutting down. This will need to be rethought slightly if we implement suspend/resume support within vr(4). This appears to fix the vr_shutdown() panic on SMP machines. My theory here is there's a race somewhere during vr_detach() with vr_intr() in the SMP case which was sometimes being triggered, although quite why this was happening is unclear (vr_stop() also explicitly disables interrupts by writing to the IMR register).
