When I shut down my system and reboot, it tells me that partition /dev/hdb2 (my root partition) was not cleanly unmounted and forces an fsck. There are LOTS of errors. Last time it said I should fsck manually because it couldn't fix everything. I find this odd for a couple of reasons: 1) I shutdown the system. I didn't just power it off. 2) The root partition is ext3. Normally it SKIPS checking an ext3 partition unless you tell it otherwise. I had recently updated my system to the latest version of Gentoo, but I can't recall if this happened before the update or not. I just checked my fstab and mtab files, and they correctly refer to /dev/hdb2 as an ext3 partition. Also, I first noticed it after rebooting from within KDE 3.01. I can't tell if it will do it if reboot while not running KDE, but my root partition had so many errors last time I'm almost afraid to restart again. Any help you could offer will be greatly appreciated!
I rebooted with the rescue CD, fsck'ed the partition, then rebooted the system 3 times. Once from the CD, once from the CLI, and once from with KDE. There were no other apparent problems. If it happens again, I'll re-open this bug report, but it appears to be working for now. (Still, I did not at any point crash my system or reset it without shutting down properly. Not sure where the file system errors came from. At least they're gone for the time being. :)
