--- Comment #23 from Clemens Fruhwirth clemens@endorphin.org --- (In reply to Michel Dänzer from comment #22)
BTW, I assume Mesa 10.1.5/6 and the current Git 10.1 branch are not affected?
I tried my best to bisect it down, but the bisection over last month again was unstable and took a long time to qualify a result, all in midst of other software changes.
I say screw it, upgraded everything to latest stable, and no more lockups. From my side, this bug can be closed.
