You have three leaf devices sharing an interrupt (audio, Intel i915 graphics and one USB controller). One of the devices is interrupting at a fairly regular rate of 165Hz, where in Chris's case one device has the interrupt stuck on.
Your performance problem may have more to do with the Intel DRM driver support discussed in other threads.
