I have a Phenom II X4 955 Black Edition installed in a ASUS M4N78 Pro Motherboard.  Currently running openSUSE 12.1 (x86_64).

It has been running fine for about 2.5 years.  About 3 weeks ago I started getting these errors

[297341.701029] [Hardware Error]: cache level: L2, tx: GEN, mem-tx: SNP
[297341.701040] [Hardware Error]: Machine check events logged
[297566.701021] [Hardware Error]: MC2_STATUS[Over|CE|-|-|AddrV]: 0xd40000000000017a
[297566.701026] [Hardware Error]: Bus Unit Error: EV error during data copyback.
[297566.701029] [Hardware Error]: cache level: L2, tx: GEN, mem-tx: EV
[297566.701039] [Hardware Error]: Machine check events logged


I tried updating to the latest kernel, but the errors continue.  These errors repeat every few minutes and sometimes cause running processes to crash.

I have about 3 months left in my waranty.  It appears to be some sort of hardware problem.  What can I do to isolate if this is a problem with the CPU?

If it's under warrenty, then there is no need to diagnose it yourself.

Even if you could, there isn't often much that you can do about it (assuming it's hardware related).

The RMA process can be found here. There are 'continue' links on each page.
