Re: [PATCH 1/1] Fix HARD Lockup Firing off while in debugger

[Jeff Merkey]

FYI.  More info, this bug only occurs when the processors have all
triggered on an int1 exception (do_debug) and are all spinning waiting
to access the debugger console .  It seems to be related to the nmi
handler firing off on processors which are waiting to get the shared
debugger lock in each debugger.

It does affect processors which may be in both nmi handlers and int1
handlers concurently but is triggered when more than one of the
processors has an outstanding int1 exception.
