I've no problems with that. The thing that I'm trying to improve here is the
fact that from lockdep's point of view there are no false positives. lockdep
reports the problem and then waves good bye. It disables itself. There might
be some real suspend locking problems on some particular setups, but it's
hard to tell, because console startup blows up the lockdep first.
