Not sure whether the lockdep patches or something else is causing this
as I haven't checked w/o the patches yet, but I seem to be having some
confusion of printk timestamps:

Tried reverting the patches ?

No, not yet, I'll do that later today.

Yes, these entries really were printed in that order. Btw, what's with
the unknown ioctls?

Proably ioctl's that lack a 32 bits conversion, you'll have to dig in
the pty stuff to find out which ones it is and if it can be a problem...

Yeah, I'll have to see, I just thought Arnd might already know :)
