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.
