Subject: MCE triggered with v3.1 and v3.2 on Xeon E5

Hi,

I am having some trouble with Linux v3.1 and v3.2[0] on a machine
based on an E5-1650. I want to bench this platform with hackbench, but
both kernel crashes on the following MCE:

The BIOS on this platform is fairly recent:

Supermicro X9SRE/X9SRE-3F/X9SRi/X9SRi-3F BIOS Date:02/10/2012 Rev:1.00

Currently, I would suspect an hardware issue as the machine is brand
new. I'll see if v3.3 trigger the same MCE and eventually run a
memtest.

Any hints and/or suggestion appreciated.

Thanks,
 - Arnaud

[0]: other kernel might be affected, but I do not have explicit logs
of crashes on those.
