Looks like this may already be fixed in mainline by the following commit:
commit b417c9fd8690637f0c91479435ab3e2bf450c038
Author: Ingo Molnar <mingo@...e.hu>
Date: Tue Sep 22 15:50:24 2009 +0200
x86: mce: Fix thermal throttling message storm
Can you confirm that please, either by compiling current git or by applying
that commit on top of 2.6.31.1?
Ingo: is that patch already scheduled for stable?
Cheers,
FJP
