Hi Andrew, sounds like something ate your journal. Is this a single
drive system? Could the drive in question be starting to fail?
I would suggest booting from a CD, backing up your /usr and re-creating
your ext3 file system. You can replace your /usr data after the new
filesystem is confirmed in place and functioning.
Oh yeah, and don't forget to backup your data religiously and check for
signs of disk failure...
If you see any future suspicious behaviour you might want to decide on
either testing the drive further or simply tossing it.
Good luck!
Me.
