[Bug 373245] Re: karmic: wakeups : hrtimer_start_range_ns (tick_sched_timer)
The number of wakeups is dependent on HT, when disabling Atom N280 hyperthreading, the number of hrtimer_start_range_ns (sched_timer) wakeups falls 4-fold (from 60 - 15 per second) therefore it might be inefficient scheduling for Atom hyperthreading in linux kernel. -- karmic: wakeups : hrtimer_start_range_ns (tick_sched_timer) https://bugs.launchpad.net/bugs/373245 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

If users here are looking for a work-around you can try to disable the hyperthreading in your Atom based laptop and report back if this helped -- karmic: wakeups : hrtimer_start_range_ns (tick_sched_timer) https://bugs.launchpad.net/bugs/373245 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I found that the problem disappeared when I removed the Mono applications/libraries, Ubuntuone, couchDB And I am not running saned, rsync, speech-dispatcher in /etc/rc2.d/ (CouchDB is uninstalled now) I still do not know which of these caused the problem. Anyway, the battery time is now over 6 1/2 hours when full (more than Windows XP), and the wakeups are about 26 / sec -- karmic: wakeups : hrtimer_start_range_ns (tick_sched_timer) https://bugs.launchpad.net/bugs/373245 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Reported to bugzilla.kernel.org as bug #14424. The bug exists also with mainline vanilla kernel 2.6.32-999-generic #200910171000 SMP Sat Oct 17 09:56:20 UTC 2009 i686 GNU/Linux. Please help to solve this by commenting at http://bugzilla.kernel.org/show_bug.cgi?id=14424, especially if you have different hardware. (EEE 1008ha here). I am not sure if this is processor-specific. ** Bug watch added: Linux Kernel Bug Tracker #14424 http://bugzilla.kernel.org/show_bug.cgi?id=14424 -- karmic: wakeups : hrtimer_start_range_ns (tick_sched_timer) https://bugs.launchpad.net/bugs/373245 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

firespeaker: did you disable it in kernel? It was solved for me when I disabled it in BIOS. -- karmic: wakeups : hrtimer_start_range_ns (tick_sched_timer) https://bugs.launchpad.net/bugs/373245 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
