Re: [gentoo-user] [Hardware Error]: MC1 Error: Copyback Parity/Victim error.

[Ralf Ramsauer]

I had a deeper look into the kernel sources:

Your error message is exactly thrown by
static bool k8_mc1_mce(u16 ec, u8 xec)

So probably you have a K8 ;-)

Have a look at:
http://www.redhat.com/archives/rhelv5-list/2007-October/msg00075.html

It *might* be an error concerning ECC error correction. Did you recently
change any hardware?

Could you attach your /proc/cpuinfo?
