The exact locking case in CPUfreq drivers causing a splat is described
in the patch. Details were already included, that's why term "more
details" was used.

This is not exactly taking us closer to a fix, so I'd rather like to
discuss about the possibility of adding one more member to task_struct.
I added Oleg as CC to catch his attention to re-evaluate based on the
previous discussion in this thread.
