Subject: [PATCH] Don't trigger NMI watchdog for panic delay
Date: Sun, 3 Aug 2003 11:38:57 +0200 [thread overview]
Message-ID: <20030803093857.GA11181@averell> (raw)
In some cases panic can be called with interrupts off. Don't trigger
the NMI watchdog in this case when a panic= parameter is specified.
