No, deadlock isn't fixed yet. Just was nerved that it didn't apply when I 
wanted to test it. :)

And to the lockdep stuff. It is a real nice feature (I used it partly when 
debugging another kernel module), but as I noticed the mathematical 
correctness check is disabled on uml and cannot be enabled due to some 
dependency problems. :(

It is real a problem because uml is a preemption-less uniprocessor kernel and 
thus the spinlocks are just NOPs - so it is quite useless for any debugging of 
them. So back to the "lets crash my working machine" and/or qemu-based tests.

Best regards,
