I have been doing some work on kgdb to pull a few of it "fingers" out of various places in the kernel. This is the final location where we have a kgdb intercept not covered by a notify.

I like the idea, but the hook should be in die_nmi(), not in the
watchdog, using the reason that is already passed into die_nmi.
die_nmi() is also called for a real NMI.

I had though that too, but it does not allow recovery (i.e. lets reset the watchdog and try again).

Hmm.. just looked at traps.c. Seems die_nmi is NOT called from the nmi trap, only from the watchdog. Also, there is a notify in the path to the other nmi stuff.
