After that the desktop is extremely laggy, no vsync (moving windows moves several blocks), scrolling is slow as hell. I only get normal behaviour by restarting X.

Certain operations will be unavailable (accelerated GL, vsync, etc), but for everything else it should fallback to a shadow buffer and for typical rendering although it may be an order of magnitude slower it shouldn't actually impact upon latency. Moving windows and scrolling should still be crisp. So if you can, please grab a 'sudo perf record -f -g -a' after such an event.

The most obvious cause for the GTT reads would be the DRI2 copies, but having that confirmed would have been useful. However, those cannot be eliminated due to the API constraints. So other than working around the broken hw, we also need to prevent the false positive EIO - which should be fixed in v3.9.
