Strange... I did experience the crash at ADB probe time here, and fixing
that bit in the cpufreq code fixed it for me ... from what I dug out, it
was apparently the interrupts not working any more, though it would
"resume" when kicked by a direct call to do_IRQ, and I suspected we were
basically losing them during the freq. transition.
Now you seem to claim something else is going on...
At this point I don't have a clue. I'll go through the patch again see
if I can find anything ...
