[Intel-gfx] [regression?] i915 generating wakeups even when idle

[Andrew Lutomirski]

Hi all-

Somewhere between Fedora 13 (with 2.6.35, I think) and Fedora 14 +
2.6.36.1, i915 started generating exactly 50 interrupts per second
(suspiciously equal to my refresh rate) when X is running.  I have the
Xorg driver 2.12.0 (specifically
xorg-x11-drv-intel-2.12.0-6.fc14.1.x86_64).  When I switch to a text
console but leave X running, the interrupts stop.

Any ideas what to look at?
