Description Mark Janes 2016-12-15 15:09:57 UTC 
GPU hangs have been observed in the following tests on SNB:

piglit.spec.ext_framebuffer_multisample.accuracy all_samples stencil_draw small

piglit.spec.ext_framebuffer_multisample.accuracy 4 stencil_resolve small depthstencil

I don't have much information, because the hangs are intermittent.  These systems run an older 4.3 kernel with an improved hangcheck mechanism from Mika.  I'll update them and verify that it still hangs occasionally.

First seen December 12 2016 on mesa_master.
Comment 2 Mark Janes 2017-01-24 22:43:32 UTC 
I will verify that this is not a regression that blocks mesa 17
Comment 3 Mark Janes 2017-01-30 18:02:58 UTC 
The gpu hangs have not been observed in recent CI results.
