these 47 could well be ALSA sound.. do you have some sound thingy active? (even if you're not playing sound) It seems to be "/usr/bin/esd -nobeeps" because killing it silences all "CK804" interrupts. The parent process is /usr/bin/gnome-session. The sound-related kernel modules that are loaded are: ----- /sbin/lsmod | grep snd snd_intel8x0 30821 3 snd_ac97_codec 93821 1 snd_intel8x0 ac97_bus 6337 1 snd_ac97_codec snd_seq_dummy 6725 0 snd_seq_oss 30673 0 snd_seq_midi_event 9929 1 snd_seq_oss snd_seq 46361 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event snd_seq_device 10325 3 snd_seq_dummy,snd_seq_oss,snd_seq snd_pcm_oss 38625 0 snd_mixer_oss 16969 1 snd_pcm_oss snd_pcm 65389 4 snd_intel8x0,snd_ac97_codec,snd_pcm_oss snd_timer 20957 3 snd_seq,snd_pcm snd 45189 13 snd_intel8x0,snd_ac97_codec,snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer soundcore 9761 1 snd snd_page_alloc 11209 2 snd_intel8x0,snd_pcm ----- AC97 power-saving mode was invoked. ac97 power saving doesn't actually kick in until userspace stops using the sound device....... and it seems esd is doing exactly that. It should close the sound device if it's not using it. (In reply to comment #3) > ac97 power saving doesn't actually kick in until userspace stops using the sound > device....... and it seems esd is doing exactly that. It should close the sound > device if it's not using it. No. ALSA shouldn't be generating interrupts when nothing is writing to the device. *** This bug has been marked as a duplicate of 253445 *** |
Description of problem: powertop reports that nVidia CK804 usb wakes up 47/second on an "idle" Gnome Desktop. Nothing is plugged in to any USB port. Both keyboard and mouse are PS/2; reboot, disconnect PS/2 cables, replace with USB keyboard and USB mouse has no effect. Ethernet is using a PCI card with e100 driver (not the builtin CK804 connection); forcedeth has been rmmod. Version-Release number of selected component (if applicable): kernel-2.6.23-0.104.rc3.fc8 How reproducible: always Steps to Reproduce: 1. powertop; kill sealert; set AC97 powersave; filesystems mounted 'noatime' 2. 3. Actual results: PowerTOP 1.7 (C) 2007 Intel Corporation Collecting data for 5 seconds < Detailed C-state information is only available on Mobile CPUs (laptops) > P-states (frequencies) Wakeups-from-idle per second : 119.0 no ACPI power usage estimate available Top causes for wakeups: 51.8% ( 46.8) <interrupt> : ohci_hcd:usb1, NVidia CK804 15.0% ( 13.6) at-spi-registry : schedule_timeout (process_timeout) 13.7% ( 12.4) X : do_setitimer (it_real_fn) 3.1% ( 2.8) gnome-terminal : schedule_timeout (process_timeout) 2.2% ( 2.0) <kernel core> : clocksource_register (clocksource_watchdog) 2.0% ( 1.8) <interrupt> : libata 1.8% ( 1.6) setroubleshootd : schedule_timeout (process_timeout) 1.1% ( 1.0) dhcdbd : schedule_timeout (process_timeout) 1.1% ( 1.0) <kernel core> : queue_delayed_work_on (delayed_work_timer_fn) Expected results: No interrupts when no relevant devices are active.
