I tend to use mcelog to get more detailed results.  Unfortunately this is
missing the first line which contains the bank number and status register, so
I can't provide any extra details.

I really should make a port of mcelog, but the patches I have to it aren't a
complete port.

Probably, though mcelog output would be better.

ignorant?

Given that it is correctable it probably isn't an issue.  It was not
reported in earlier releases, so there is a chance that this could have been
happening previously.
