Hello, this bug also affects me. I'm running Jaunty with kernel 2.6.30-5candela on an Acer Aspire One. According to xorg.log i'm using EXA. If you need me to try anything I'm willing to do it.

[Bug 373245] Re: wakeups kernel core : hrtimer_start_range_ns (tick_sched_timer)
I did some testing with UXA and EXA (Not XAA) during jaunty with it's kernels and .30 and it was still present. If it's in intel driver issue then it's present in both EXA and UXA. UXA is currently the only supported option with 2.8 afaik.

[Bug 373245] Re: wakeups kernel core : hrtimer_start_range_ns (tick_sched_timer)
Is everyone who is seeing this issue using an Intel graphics device and using UXA? I'm using Jaunty, with a 2.6.30 kernel (from the kernelteam PPA) and X and Intel drivers from the xorg-updates PPA. (xserver-xorg-video- intel=2.7.1). I also appear to see this issue (many interrupts) as described by the OP. Because I am using 2.7.1, I'm able to switch back to EXA; the extraneous interrupts disappear and in particular I get normal battery life again. I believe the xorg-video-intel 2.8 driver in Karmic still supports XAA (EXA support has been removed). Could those affected try XAA (yes, the performance will be terrible) and report whether the extraneous interrupts exist? For this bug to be fixed, it's extremely important to keep it on-topic. In particular, limiting discussion to configuration similar to the reporter (Intel graphics UXA). Political discussions (e.g. what Ubuntu's priorities are, whether this bug is important, etc) should also be done elsewhere. -- wakeups kernel core : 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
[Bug 373245] Re: wakeups kernel core : hrtimer_start_range_ns (tick_sched_timer)
Thanks Samat, I would like to try this, but please could you clarify how to enable XAA support? I've tried using Option AccelMethod xaa in my xorg.conf, but it seems to make no difference - the logs still show: (II) UXA(0): Driver registered support for the following operations: (II) solid (II) copy (II) composite (RENDER acceleration) and there is no mention of XAA in the logs. I'm on a Lenovo x200 using Jaunty with kernel 2.6.31-020631rc7-generic from the kernelteam PPA and Intel driver 2.80 from https://launchpad.net/~morgwai/+archive/jaunty-backports -- wakeups kernel core : 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
[Bug 373245] Re: wakeups kernel core : hrtimer_start_range_ns (tick_sched_timer)
Sorry, just seen that XAA and EXA have been removed from Intel's 2.80 driver. From the release notes: The driver now depends on X server 1.6 or later, and eliminates several obsolete code paths, (XAA and EXA removed in favor of UXA, DRI1 support eliminated). http://lists.freedesktop.org/archives/xorg/2009-July/046534.html -- wakeups kernel core : 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
[Bug 373245] Re: wakeups kernel core : hrtimer_start_range_ns (tick_sched_timer)
I guess it really depends on how important battery life of notebooks is for this release. I would anticipate that with the push on net books and laptops it would be reasonably important. The battery life has been slowly getting better since Hardy but it still does make a significant difference. -- wakeups kernel core : 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 think part of the problem here is it seems to be a regression. I know; for me at-least, when i was running Jaunty on my netbook i was seeing 6-7hr battery life. After upgrading to Karmic (with this bug present) I'm seeing 4.5-5hr battery. Ideally I think we should be on-par with; or better than, windows on any given hardware. Jaunty was pretty close, I think with windows i was getting about 7hrs. -- wakeups kernel core : 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
Re: [Bug 373245] Re: wakeups kernel core : hrtimer_start_range_ns (tick_sched_timer)
I don't think i have ever gotten anywhere close to that especially with Jaunty. 2.6.30 was probably the best kernel for the X200.
