I had this problem recently with a few systems. Try booting to
single-user mode, and then do the following command:
tune2fs -j DEVICE-FILE-WITH-PROBLEM
This will create a new journal on the filesystem. I haven't tracked
down why the journal disappears yet, but it seems to, and then the
system (of course) won't mount it as ext3.
