Synopsis: [hal]: Periodic crashes of system at working HAL

State-Changed-Why: 
I examined similar (not to say the same) backtraces and I am sure that
the problem is caused by nvidia driver. Invalid reference counting for
cloned devices in dev_clone handler destroys devfs list of devices,
and consequent access to /dev mount point causes read from freed memory
and traversal of destroyed list.

Please, remove the nvidia driver from the system, and report whether the
panics disappear.
