Bah, foiled again.

You can try 'echo 1 | sudo tee /sys/kernel/debug/dri/0/i915_wedged'
to grab an i915_error_state. It may or may not actually wedge the
machine. Caveat tester.

However, if you are reasonably confident that a change in mesa provokes
the issue, you can bisect the commit in question. That may give another
clue as to where to look next.
