Subject: [PATCH 0/2] touch_nmi_watchdog semantic changes
Date: Tue, 4 Jan 2011 22:38:29 -0500 [thread overview]
Message-ID: <1294198711-15492-1-git-send-email-dzickus@redhat.com> (raw)
I was trying to change the semantics of how touch_nmi_watchdog worked
to cover a corner case where endless console writing would block the
watchdog from going off.
Ingo recommended that I add ratelimiting to the panic code to in case we
get a slew of locked up cpus, hence my first patch in the series.
Cheers,
Don

panic: ratelimit panic messages
watchdog: touch_nmi_watchdog should only touch local cpu not every
one
