Judging from the problem description, this is the 8xx pageflipping bug. Should
be fixed in 3.5:
commit c2798b19bac2538393fc932bfbe59807a4734b3e

drm/i915: i8xx interrupt handler
gen2 hardware has some significant differences from the other interrupt
routines that were glossed over and then forgotten about in the
transition to KMS. Such as
- 16bit IIR
- PendingFlip status bit
This patch reintroduces a handler specifically for gen2 for the purpose
of handling pageflips correctly, simplifying code in the process.
v2: Also fixup ring get/put irq to only access 16bit registers (Daniel)
