            Bug ID: 99099
           Summary: [SNB] intermittent gpu hang in
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: intel-3d-bugs at lists.freedesktop.org
          Reporter: mark.a.janes at intel.com
        QA Contact: intel-3d-bugs at lists.freedesktop.org

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

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.
