Do you also have lm-sensors installed? Running sensord? Genuine CPU issues seem pretty rare, so I would check for overheating or power issues, and lm-sensors will help with that.

I periodically get mce errors on my i980 machine when running big PixInsight jobs and I hit thermal limits. I'd suggest you run extensive memory tests and if you don't see any problems don't worry too much. Of course, it's always wise to do good backups in case the problem gets worse. Good luck, Mark

From the manpage: Most errors can be corrected by the CPU by internal error correction mechanisms. Uncorrected errors cause machine check exceptions which may kill processes or panic the machine. A small number of corrected errors is usually not a cause for worry, but a large number can indicate future failure. When an uncorrected machine check error happens that the kernel cannot recover from then it will usually panic the system. In this case when there was a warm reset after the panic mcelog should pick up the machine check errors after reboot. This is not possible after a cold reset. If you are overclocking, try disabling it.
