All of a sudden, after a reboot, I noticed my keyboard stopped working. Please see the applicable dmesg, below. A lot of unknown symbols all of a sudden. I did not recompile my modules or anything... Anthing like this happen to anyone else?

Update: Now that I properly remember, I ran generate-modprobe.conf since I did not have a modprobe.conf and I'm on 2.6.10, and my bttv module options were not working in modules.conf. This probably has something to do with it. On that note, do I need a modules.conf?

Move modprobe.conf to other place or rename it and see what happens...
