From dbc018eca386b4e2670fc3116feada19f3db664c Mon Sep 17 00:00:00 2001 From: Naga Chumbalkar Date: Tue, 9 Aug 2011 22:27:26 +0000 Subject: watchdog: hpwdt: prevent multiple "NMI occurred" messages On platforms with no iCRU support don't print two, (possibly conflicting), "NMI occurred" messages when the firmware is unable to source the NMI. Please note that one of the enhancements to the v1.3.0 hpwdt driver is to panic and allow KDUMP to succeed even on NMIs that are unknown to the platform firmware.
