Subject: [CentOS] Kernel:[Hardware Error]:



I had a series of kernel hardware error reports today while I was away
from my computer:

kernel:[Hardware Error]: MC2 Error: VB Data ECC or parity error.

kernel:[Hardware Error]: cache level: L2, tx: DATA, mem-tx: EV

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!
