It actually got too hot to place on my legs. Powertop showed it running over a 1000 wakeups a second while completely idle. Chuck Ebbert pointed me at this diff.. http://git.kernel.org/?p=linux/kernel/git/x86/linux-2.6-tip.git;a=commitdiff;h=396e894d289d69bacf5acd983c97cd6e21a14c08 which brings it back down to a much more respectable 80 wakeups a second. Is this lined up for 2.6.35.1 ?
