The lockdep problem has been fixed, yes.

The system lockup...I'm not sure.  I can't reproduce it with lockdep
enabled, and I get no gripes.  I'm going back to a non-lockdep kernel
just to see if that's actually involved at all, or whether the problem
(which hit me several times) has somehow just evaporated.
