The patch which is being discussed seems to be this one: commit 7467571f4480b273007517b26297c07154c73924 Author: Tero Kristo <tero.kri...@nokia.com> Date: Thu Feb 24 17:19:23 2011 +0200
cpuidle: menu: fixed wrapping timers at 4.294 seconds Cpuidle menu governor is using u32 as a temporary datatype for storing nanosecond values which wrap around at 4.294 seconds. This causes errors in predicted sleep times resulting in higher than should be C state selection and increased power consumption. This also breaks cpuidle state residency statistics. cc: sta...@kernel.org # .32.x through .39.x Signed-off-by: Tero Kristo <tero.kri...@nokia.com> Signed-off-by: Len Brown <len.br...@intel.com> This patch seems to be in 2.6.38.8 and 2.6.39.1 stable updates which should be included in official kernels in the next few weeks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/760131 Title: Power consumption raised significantly in natty -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
