powertop records who started the timer, not who is currently running (this can be confusing indeed) sounds like the ondemand timer. in 2.6.21, the ondemand timer would indeed wake your cpu up in 2.6.22 this got fixed so that the ondemand timer only fires if other timers would fire as well in 2.6.23-rc this got improved so that powertop can now find out about the "only if other" behavior so it's sort of a work in progress, but if you run the 2.6.22 kernel, the number will be less than what the other things in your system are doing, and they're not actual "real" wakeups.. _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
