Well, I was about to rant half an hour ago about people complaining here without understanding the issue, but Richard clearly explained the issue - thanks for that.
As for other ditros, I just booted my Arch Linux I had installed some time ago to test this. The older powertop version 1.11 shows the wakeups as coming from "hrtimer_start_range_ns (tick_sched_timer)" instead of "[kernel scheduler] Load balancing tick", but has exactly the same numbers as the newer powertop 1.12. Arch was running 2.6.34-ARCH, my Ubuntu is running 2.6.32-24 as well as 2.6.34.1, and the figures are identical, so NO, switching the distro doesn't help! I'll rework the description in a moment to better describe the cause of the problem, list possible workarounds (namely downgrading to 2.6.31 or upgrading to -tip/Brian's ppa) and linking in the lkml threads. -- Tens of wakes per second in "[kernel scheduler] Load balancing tick" on Core 2 Duo even with only 1 core enabled https://bugs.launchpad.net/bugs/524281 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
