Not sure if I should mail to acpi@ or drm. =46rom time to time (I noticed this resuming from hibernation, but it just appeared without that), I get huge wakeups from i915 module, and huge power consumption on my Thinkpad T61 with intel 965: corsac@hidalgo: sudo powertop -d PowerTOP 1.10 (C) 2007, 2008 Intel Corporation=20 Collecting data for 15 seconds=20 Cn Avg residency C0 (cpu running) (60,9%) C0 0,0ms ( 0,0%) C1 0,0ms ( 0,0%) C2 0,0ms (39,1%) C4 0,0ms ( 0,0%) P-states (frequencies) Wakeups-from-idle per second : 41769,4 interval: 15,0s Power usage (ACPI estimate): 33,1W (0,9 hours)=20 Top causes for wakeups: 99,8% (85712,2) : i915@pci:0000:00:02.0=20 Not sure what I can do about this but it's a bit painful when running on battery :/ If I need to provide more info or ask on another list, please say so :) Cheers and thanks, --=20 Yves-Alexis --=-vKFTqnD7YfR1xNBGHsrG Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEABECAAYFAkk1ZtEACgkQTUTAIMXAW67JlACfUKq3/LasylFVAQvxvJ6OXfrq xwIAoItdV2JvGA21XyxKfZOYSTUco5x4 =FA9t -----END PGP SIGNATURE----- --=-vKFTqnD7YfR1xNBGHsrG--
