Hi! My system is a Maverick (upgraded from Lucid, upgraded from Karmic). I removed the udev rule and rebooted: % sudo powertop -d -t 30|grep hdaps 6.5% ( 50.0) [kernel core] hdaps_mousedev_poll (hdaps_mousedev_poll)
Seems hdapsd is polling for some reason, with a lot of wakeups. % sudo killall hdapsd % sudo killall hdapsd hdapsd: no process found % sudo hdapsd -t Mon Dec 13 10:06:17 2010: Dry run, will not actually park heads or freeze queue.

I will restart with udev rules again and post results. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/687282 Title: hdapsd drains unnecessary power polling /sys -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
