Comment 28 for bug 524281

I have tested the following boot options adding "idle=halt" and "processor.max_cstate=1" or cstate=2, not adding all at the same time but one after the other. None of the options aren't fixing the wakeups on a Core 2 Duo (E6500) or on a Pentium D (both desktop PCs).

This is what is looks like in Powertop when scrolling a page in Firefox:
Top causes for wakeups:
42,3% (115,9) [kernel scheduler] Load balancing tick

This is what it looks like when idle:
8,2% (7,0) [kernel scheduler] Load balancing tick
