Actually, that's because of an old fsck binary, which compares too
many fields in when doing a compare between the superblock and the
first spare. I warned about that in my original announcement. It's
harmless (but annoying, since the boot will drop to single user
because of a "fatal" fsck error).

The 'EBADF problem' is serious though, and I can't seem to reproduce
it myself.
