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
Collecting data for 15 seconds
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)
Top causes for wakeups:
99,8% (85712,2) <interrupt> : i915@pci:0000:00:02.0
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,

The interrupt code on i915 has been heavily rewritten. This sounds like
an interrupt that isn't being acked correctly, so the drm list is
probably your best bet.
