Subject: Very high CPU values in top on idle system (3.0-rc1)
Date: Mon, 30 May 2011 19:39:16 +0200 [thread overview]
Message-ID: <20110530173916.GA1746@x4.trippels.de> (raw)
I get very high CPU values when I run 'top' on my (mostly) idle system
with 3.0-rc1. For example mpd was always in the 1-2% range and is now
constantly over 50%.
This is caused by:
commit 317f394160e9beb97d19a84c39b7e5eb3d7815a8
Author: Peter Zijlstra <a.p.zijlstra@chello.nl>

sched: Move the second half of ttwu() to the remote cpu
When I revert the above I see sane CPU values again.
