From: Dave Jones on 4 Aug 2010 16:40 My laptop felt like it was about to burst into flames after I ran 2.6.35 on it for a while. 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 ?

Yeah, it's tagged. More trouble than it's worth, optimization dies. -Mike -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
