Agreed, though I always vote for notifier chain (with either CONFIG_ option
or command line one) so there would be a way to turn panic off if needed.
I believe there is a way to make such NMI handler being with highest priority
and Ying will be able to do with it whatever he wants -- panic, warning,
or even immediate reboot, whatever ;)
