The error message you saw was ext2 saying "I don't know how to deal with
uncleanly shut-down ext3 filesystems".

The kernel will try to mount the fs as ext3 first, and then as ext2.

For some reason the ext3 attempt is not successful, so it falls through to
ext2 and that is the first message we see.
