there is a bug that causes powertop to count the timer ticks as separate wakeups, while in fact those timer ticks are due to something else in the wakeup list causing the timer to trigger, hence, the list can contain up to twice as much wakeups as really occurred. _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
