Since vmx blocks INIT signals, we disable virtualization extensions during reboot. This leads to virtualization instructions faulting; we trap these faults and spin while the reboot continues. Unfortunately spinning on a non-preemptible kernel may block a task that reboot depends on; this causes the reboot to hang. Fix by skipping over the instruction and hoping for the best.
