Wakeups-from-idle per second : 403.4 interval: 10.0s Power usage (ACPI estimate): 26.0W (1.6 hours) (long term: 31.9W,/1.3h) Top causes for wakeups: 54.2% (412.4) <kernel core> : hrtimer_start_range_ns (tick_sched_timer) 16.9% (128.6) <interrupt> : PS/2 keyboard/mouse/touchpad 12.4% ( 94.4) <kernel IPI> : Rescheduling interrupts 3.9% ( 29.4) firefox : hrtimer_start_range_ns (hrtimer_wakeup) 3.4% ( 26.0) <interrupt> : extra timer interrupt 2.5% ( 19.0) Xorg : hrtimer_start_range_ns (hrtimer_wakeup) laptop-mode enabled I see similar issues reported on Ubuntu https://bugs.launchpad.net/ubuntu/+source/linux/+bug/373245 and Fedora 11 and even Debian with recent kernels. Kernel bug? The only change I can think of between 11.1 and 11.2 that might have caused this is changing from kernel-default to kernel-desktop. Will switch back and report. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

http://bugzilla.novell.com/show_bug.cgi?id=530510 http://bugzilla.novell.com/show_bug.cgi?id=530510#c5 --- Comment #5 from Jan Ritzerfeld 2010-03-23 08:20:01 UTC --- @Tejas: The kernel bug report mentioned in the ubuntu tracker is https://bugzilla.kernel.org/show_bug.cgi?id=14424 @Ben: After reading the latest comments of the above mentioned kernel bug report, I quit some applications that are sometimes shown within powertop. Especially nepomukservices took about 2W (not strigi, that was inactive)! Quitting opera helped a little bit, too. But, the number of wakeups was not that significantly reduced after that. Thus, the basic idea of the kernel bug report seems to be valid. However, while quitting nepomukservices might be a workaround for some of us, having to quit applications is not. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

openSUSE 11.2 is in security-maintenance mode. Please reopen if this issue still occurs with 11.3 or Factory.

If you wait long enough that's true for every bug is it not? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

So still a bug but maybe not a kernel one. Is there an easier way to test with timers disabled than rebuilding the kernel? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
