F15: mcelog hardware error after a power failure

[Patrick Mansfield]

Hi -

I'm running up to date Fedora 15.

Power glitched yesterday morning, and my system rebooted (along with
clocks resetting, and my laptop hanging ... but that's a different issue).

During the reboot, I got the following in my log file. The machine is otherwise
up and running with (apparently) no problems.

Any ideas what the output means? 

Could it just be a glitch caused during the power failure, and then
reported during the boot?

I haven't rebooted since this happened.

Thanks!
