Hi, I have a problem with 2.6.28-rc6-00209-g6a12141. Not sure if I
should mail to acpi@ or drm.

From 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

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,
