Public bug reported: This began happening with 13.04 upgrade. I tried xorg-edgers repository but this made matters worse. I reported the GPU hang to the kernel folks upstream. Based on the i915_error_text, they report that my hangs are due to mesa blorp operations.
The bug causes a GPU hang which requires the windowing system to be restarted.
