PS: Version-Release number of selected component (if applicable): kernel 3.2.10-2 (mistype, should be 3.2.10-3) does powertop show anything interesting ? Well, that's weird. Ich booted up today, updated the following packages: Mar 18 19:44:07 Updated: rpmfusion-nonfree-release-16-3.noarch Mar 18 21:13:29 Installed: lame-libs-3.98.4-1.fc14.x86_64 Mar 18 21:13:30 Installed: x264-libs-0.0.0-0.31.20110811.fc16.x86_64 Mar 18 21:13:31 Installed: a52dec-0.7.4-15.fc11.x86_64 Mar 18 21:13:32 Installed: libsidplay-1.36.60-2.fc15.x86_64 Mar 18 21:13:32 Installed: librtmp-2.4-0.1.20110811gitc58cfb3e.fc16.x86_64 Mar 18 21:13:33 Installed: libmad-0.15.1b-13.fc12.x86_64 Mar 18 21:13:34 Installed: xvidcore-1.3.2-2.fc15.x86_64 Mar 18 21:13:35 Installed: libva-1.0.15-1.fc16.x86_64 Mar 18 21:13:36 Installed: ffmpeg-libs-0.8.9-1.fc16.x86_64 Mar 18 21:13:37 Installed: libid3tag-0.15.1b-11.fc15.x86_64 Mar 18 21:13:38 Installed: opencore-amr-0.1.2-1.fc12.x86_64 Mar 18 21:13:38 Installed: libmpeg2-0.5.1-8.fc12.x86_64 Mar 18 21:13:39 Installed: twolame-libs-0.3.13-1.fc16.x86_64 Mar 18 21:13:40 Installed: gstreamer-plugins-ugly-0.10.18-3.fc16.x86_64 Mar 18 21:13:41 Installed: gstreamer-ffmpeg-0.10.13-1.fc16.x86_64 Mar 19 08:19:08 Updated: rpmfusion-free-release-16-3.noarch Mar 19 08:19:11 Updated: ffmpeg-libs-0.8.10-1.fc16.x86_64 Mar 19 17:43:09 Updated: liblouis-2.4.1-1.fc16.x86_64 Mar 19 17:43:09 Updated: liblouis-python-2.4.1-1.fc16.noarch and now I got an energy consumption around 9W, quite normal. I don't know why this happened. As I wrote the bug, my GPU was running on full-speed, CPU 800MHz (power save and deepest idle state). PowerTOP shows normal values, just a slight increase from 3.2.9 Daily update: Today 12W in idle (Firefox with Facebook, pdf-Reader, display brightness 33%) Powertop shows something interesting, 3% C0 power state for cpu0, 18% for cpu1 and ~900ms CPU time for /usr/libeexec/tracker-miner-fs and ~ 1000 pkts/s for network-interface wlan0 Under 3.2.9 today 8W It seems that cpupower is changing CPU-states more quickly. Governor is set to powersave but it's behaviour is more like ondemand it seems that profile is anything but idle. even if you're not touching anything, firefox and facebook will be using cpu (they use ridiculous amounts of javascript). also tracker running is obviously going to draw power as it runs around indexing things. I don't see anything kernel related here that needs fixing. If it does spike up again, do some profiling with powertop/top/iotop and find out what it's doing. If the machine really is completely idle and pulling lots of power, perhaps we can do something. |
Created attachment 570877 [details] Yum.log 03-18-2012 Description of problem: After updating to kernel version 3.2.10-3 I got around 25W energy consumption on my notebook, up from 8,5W (both Idle). I got a Sony Vaio-S with an Intel i3 (Sandy Bridge) and hybrid graphics (AMD HD 6450). I enabled RC6 and switched off the discrete gpu (AMD) using vgaswitcheroo. Version-Release number of selected component (if applicable): kernel 3.2.10-2 How reproducible: Every boot Steps to Reproduce: 1. boot up 2. idle system 3. switch on energy monitor or powertop Actual results: ~ 25W power consumption Expected results: ~ 8,5W Additional info: latest yum update attached
