Bug#613973: linux-image-2.6.37-1-686: Disturbing [Hardware Error] MCE messages in 2.6.37
Package: linux-2.6
Version: 2.6.37-1
Severity: normal
Hi,
After upgrade to 2.6.37, I started having tons of errors like those shown
below, about MCE. This happens in all terminals, in a sid box that did not
show this problem until 2.6.37 is installed.

Browsing a bit about this, seems that Andi Kleen patch in
http://git.kernel.org/?p=linux/kernel/git/ak/linux-mce-2.6.git;a=commitdiff;h=6e3c7411d2b86bff210c59caa432e8e862037bfd
may help.
Pointed to it by last question in

Sending minimal info because above info seems enough. Let me know if
extensive info is needed. Running on AMD K7.
