I wasn't able to reproduce it with fglrx for now. Here is the dmesg when the
radeon driver is used:

Ok, let's see what kind of errors does your machine report. It looks
like benign GART TLB walk errors but let's verify that first. Can you
apply the following patchlet and re-trigger the problem:

--
diff --git a/drivers/edac/edac_mce_amd.c b/drivers/edac/edac_mce_amd.c

Yep, this is a benign GART TLB error which is not being reported but
you're using the amd64_edac module and it trips since the error is still
being logged and the module sees it. There are two fixes:

1. If you have a BIOS option with a wording like:

"Gart Table Walk Error MC reporting: Disabled/Enabled."

which should disable it.

2. If no BIOS option, the patch below should fix it. Can you please
test (against v2.6.32).

Thanks.
