Can anyone tell me how to decipher this which has appeared in dmesg?
Google wasn't very helpful.

Looks like machine check error, it detected an error in the L1 cache
on your CPU.

Since it says "Corrected error, no action required" I would not worry
about it. If that makes you feel any better. :)

What kind of architecture / CPU?

I suppose it's an AMD CPU as this error is thrown by
"drivers/edac/mce_amd.c":

$ cd /usr/src/linux; fgrep -R "MC1 Error"
drivers/edac/mce_amd.c: pr_emerg(HW_ERR "MC1 Error: ");

$ fgrep -R "Copyback Parity/Victim error"
drivers/edac/mce_amd.c:                 pr_cont("Copyback Parity/Victim
error.\n");

since those errors are rare, I would worry about it.

I share this opinion.
The message says - even if the error was corrected - that there's
something dramatically wrong with your - i suppose - CPU.
"Corrected error" might imply, that some low-level feature got disabled
in order to prevent furher errors.

Does this error appear only once at early boot or frequently?

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?

I read it, that one sounds like a correctable ECC RAM error.

No hardware changed in a very long time.

> Could you attach your /proc/cpuinfo?

Sure, I've attached it.  I'm changing hosts and machines shortly and
I've only seen this error once so I'm thinking I don't need to take
action.

A friend of mine told me, that AMD also had some trouble concerning TLB
on that architecture (translation lookaside buffer).
Unfortunatelly I have no references for that issue.

I would keep a eye on that error, and if your system must be
highly-available, i would even change hardware.

Completely unrelated. He got a Cache ecc error. Not tlb Bug. Also those
were fixed quickly. In hardware and software. No Problem There. I hate Auto
correction.
