I just don't like using BUG(). BUG() means that if we continue we will
corrupt the filesystem or make you go blind. WARN and returning here
should not cause any harm and will even let those with X terminals see
oops in /var/log/messages.
Uh, NO.
If this is wrong something in the kernel code stream is corrupted (heck,
you might just have caught a rootkit!)
Die. NOW.
