The keyword here is 'before'. When we enter the interrupt handling there has already been unclaimed register access. Please try with i915.mmio_debug=1000000. If you don't get any 'after' ones, then it is likely that some userspace lib does hardware access without coordinating with driver.

I found something.... I took a closer look at what mplayer was doing. It tries to use vdpau for accelerated video playback. However that failed and it fell back to XV. A bit of googling pointed at libvdpau-va-gl1, which i did not have installed. Installing that, vdpau gets translated to VA, and accelerated video decode works and no more stack trace. My guess is, whatever mplayer is doing when vdpau fails is causing the stack trace? So you might be able to reproduce the issue by removing libvdpau-va-gl1? I will let you decide if you want to set this as resolved, or if you want to try to dig deeper now that you might be able to reproduce it.
