I can still reproduce this on i965 using kde4 opengl compositing window
manager. It runs for some time at 7-180 irqs/s only to suddenly jump to >60000
irqs/s.
I am using 2d7748e0c968da5e8ed3dab61d40b9909e3d5c7e of drm-intel(which is
currently what for-airlied points to).
On the plus-side, the interrupt-handler feels responsible for the interrupt, so
the kernel does not disable it, until under heavy load(i.E. loading a complex
website with konqueror leads to the kernel disabling the interrupt).
