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!
