Assigning to Mesa product (please let me know if I am mistaken with this GPU Hang).

From this error dump, hung is happening in render ring batch with active head at 0x76a68390, with 0x7a000003 (PIPE_CONTROL) as IPEHR.

Please test a new version of Mesa (12 or 13) and mark as REOPENED
if you can reproduce and RESOLVED/* if you cannot reproduce.
