[sles-beta] Problems with mcelog on HP-Proliant Server with AMD Opteron processors

Hi,
newer AMD processors, family 16 and greater, do not support mcelog,
on SP2 mcelog was just missing the check and the errormessage.
The message is not really helpful at the moment since we don't ship
edac_mce_amd with the SLES kernel. For now, please just disable mcelog.
OTOH, no harm is done if mcelog starts on AMD systems, it will just bail
out with that message, nothing else is affected.
We're tracking that with bnc#807336, AMD is involved.
