Other than wondering whether powertop has issues similar to the bug
Steven Rostedt located, I must confess myself clueless. Here are some
diagnostics I can suggest:
1. Run in 32-bit mode. This disables some of the new adaptive-ticks
functionality, so might give a probabilistic indication of where
the bug lies.
2. The standard fallback of bisection.
Would you be willing to do either of these?
Thanx, Paul
