Just a me-too report. i am also getting this as the top of the list when seen with powertop.

Average around 43 is the number of wakeups/sec from [Kernel Scheduler] Load Balancing Tick.

I don't want to disable compiz, so haven't yet tried out the workaround as at-least for me, that's not a solution.

Pls. let me know if anything more is needed in terms of details about the system and I will gladly provided.
