Subject: i386, v3.6-rc3: Kernel panic - not syncing: Fatal exception in interrupt
Date: Mon, 27 Aug 2012 17:14:27 +0200	[thread overview]
Message-ID: <20120827151427.GE8285@erda.amd.com> (raw)

Steven and Ingo,

while running profiling tests on 32 bit I got a

 Kernel panic - not syncing: Fatal exception in interrupt

The remainings of the stackdump are:

 Kernel panic - not syncing: Fatal exception in interrupt

Suspected patches are the following:

 $ git shortlog -p --full-diff v3.5..linux/master -- arch/x86/kernel/nmi*
 Ingo Molnar (1):
       Merge commit 'v3.5-rc3' into x86/debug
 
 Li Zhong (1):
       x86/nmi: Clean up register_nmi_handler() usage
 
 Steven Rostedt (2):
       x86: Remove cmpxchg from i386 NMI nesting code
       x86: Save cr2 in NMI in case NMIs take a page fault (for i386)

Do you know already of something similar?

This happened to me the 2nd time now. Will try to reproduce it to get
a complete trace.
