Subject: excessive wakeups in 2.6.35
Date: Wed, 4 Aug 2010 16:38:11 -0400 [thread overview]
Message-ID: <20100804203811.GA6479@redhat.com> (raw)
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 ?
Dave
