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.

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