Full specs: http://www.samsungpc.com/gb/support/r20/specs/r20spec.pdf Intrepid with kernel 2.6.27-7-generic Linux r20 2.6.27-7-generic #1 SMP Tue Nov 4 19:33:20 UTC 2008 i686 GNU/Linux PowerTOP reports ~50000(!) wakeups-from-idle per second, while the six top causes for wakeups shown in the default view only add up to approx. 100. Avg residency for an idling system is ~60% "C0 (cpu running)", ~40% C2. Adding the noapic kernel option results in only the aforementioned ~100 wakeups being listed, and ~99% C2. Cooling fan then alternates between low and medium speed, while it never slows down without noapic. ** Attachment added: "lspci-vv.txt" http://launchpadlibrarian.net/19863287/lspci-vv.txt -- Powertop reports huge number of wakeups and drains battery https://bugs.launchpad.net/bugs/145377 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
