I am joining the confused camp. With Linux 2.6.25-rc3-g18a4bf0 and the ipw2200 I get the following when Wifi is OFF (phycical switch) PowerTOP 1.9 (C) 2007 Intel Corporation Collecting data for 60 seconds Cn Avg residency C0 (cpu running) ( 0,4%) C1 0,0ms ( 0,0%) C2 132,6ms (13,9%) C3 154,8ms (85,7%) P-states (frequencies) 1,71 Ghz 0,1% 1400 Mhz 0,0% 1200 Mhz 0,0% 600 Mhz 99,9% Wakeups-from-idle per second : 6,6 interval: 60,0s Power usage (ACPI estimate): 11,4W (1,7 hours) Top causes for wakeups: 55,9% ( 6,8) <interrupt> : acpi 8,2% ( 1,0) apache2 : schedule_timeout (process_timeout) 8,2% ( 1,0) fluxbox : schedule_timeout (process_timeout) And when it is ON PowerTOP 1.9 (C) 2007 Intel Corporation Collecting data for 60 seconds Cn Avg residency C0 (cpu running) ( 0,5%) C1 0,0ms ( 0,0%) C2 88,3ms (99,5%) C3 0,0ms ( 0,0%) P-states (frequencies) 1,71 Ghz 0,1% 1400 Mhz 0,0% 1200 Mhz 0,0% 600 Mhz 99,9% Wakeups-from-idle per second : 11,3 interval: 60,0s Power usage (ACPI estimate): 14,0W (1,6 hours) Top causes for wakeups: 52,6% ( 11,8) <interrupt> : acpi 17,9% ( 4,0) <kernel module> : usb_hcd_poll_rh_status (rh_timer_func) 5,0% ( 1,1) <interrupt> : ehci_hcd:usb1, uhci_hcd:usb3, uhci_hcd:usb4, ipw2200 4,6% ( 1,0) fluxbox : schedule_timeout (process_timeout) 4,5% ( 1,0) apache2 : schedule_timeout (process_timeout) The becaon interval is set at 1000ms so that is not the problem. Can someone explain how to get down to C3 when using the ipw2200 driver? _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
