I had a series of kernel hardware error reports today while I was away from my computer:
Message from syslogd@fcshome at Aug 12 10:12:24 ... kernel:[Hardware Error]: MC2 Error: VB Data ECC or parity error.

never saw anything like that before.
cpu is:

six core AMD, above is one of the cores.
Any clues to figure out the errors, and/or mitigate?
thanks!
