This intermittent GPU hang began occurring around March 16 on mesa master. It has occurred on g46, ilk, snb, ivb, hsw, and bdw. Running a full test suite on Mesa's Jenkins piglit system reproduces the hang on at least one system, when run 5 or 6 times. This reproduction is not reliable enough for an automated bisect. I'm working to isolate it.
This bug was not specific enough to be actionable. All known gpu hangs have been written up in more specific bugs or fixed.
