Message-ID: <20010331033504.A7022@pcep-jamie.cern.ch> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.2.5i Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Subject says it all. On my laptop which is running 2.4.0, while the machine is completely idle "top" reports kapm-idled as usin about 45% of the CPU. The remaining 55% is reported as idle time. When the machine gets a little more active, the CPU time attributed to kapm-idled decreases while the 55% idle time increases to 85%! This is not caused be "top": I get the same 45% from "ps -l 3". I remember when kapmd was reporting 100%. Is the new behaviour intentional, and is it saving the maximum power on the laptop? thanks, -- Jamie
