http://bugzilla.kernel.org/show_bug.cgi?id=12788 ------- Comment #9 from theholyettlz@xxxxxxxxxxxxxx 2009-03-05 14:50 ------- I see a steady flow of interrupt 16 before and after suspend/resume, about 15/sec in both cases. I can't see anything else producing interrupts en-masse. 16: 40 3707 IO-APIC-fasteoi uhci_hcd:usb3, mmc0, mmc1, iwlagn, i915@pci:0000:00:02.0 Unplugging/disabling all USB devices does not appear to solve the problem. (Haven't tried reloading uhci driver, it's built into the kernel.) Here's another screenshot following suspend/resume: PowerTOP version 1.10 (C) 2007 Intel Corporation Cn Avg residency P-states (frequencies) C0 (cpu running) (55.1%) 2.11 Ghz 0.2% C0 0.0ms ( 0.0%) 2.10 Ghz 0.0% C1 0.0ms ( 0.0%) 1.60 Ghz 0.5% C2 0.0ms (44.1%) 800 Mhz 99.3% C3 0.0ms ( 0.7%) Wakeups-from-idle per second : 39692.4 interval: 10.0s no ACPI power usage estimate available Top causes for wakeups: 30.3% ( 38.0) <interrupt> : acpi 12.6% ( 15.8) <kernel IPI> : Rescheduling interrupts 12.3% ( 15.4) <interrupt> : uhci_hcd:usb3, mmc0, mmc1, i915@pci:0000:00: 11.0% ( 13.8) <interrupt> : extra timer interrupt 8.0% ( 10.0) gkrellm : schedule_hrtimeout_range (hrtimer_wakeup) 6.7% ( 8.4) <interrupt> : ata_piix I don't understand this at all --- it would appear to show no significant difference in the sources of wakeups than from the first screenshot I posed in Comment #3 --- yet claims around 200 times more wakeups in total. ...So where are they coming from? I can't see any process hogging CPU... -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
