From 99a19cf1c0eb22bad83fff060f08330ee9e029e2 Mon Sep 17 00:00:00 2001 From: Prarit Bhargava Date: Wed, 22 Aug 2007 14:34:38 -0400 Subject: [PATCH] [IA64] Stop bogus NMI & softlockup warnings in ia64 show_mem When dumping memory via sysrq-m it is possible to take a bogus NMI watchdog or softlockup watchdog because the dump can take a long time on big memory systems. Occasionally tickle the watchdog when doing the dump.
