Ingo's tree had a fix for this by increasing the lockdep chain size
IIRC. I think it's worth updating the BZ with current info, Jon?

Jon.

Well, I think this bug is supposed to have been fixed, but I'm not really sure.

That's why it's still listed.

Thanks,

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.
