          Priority: high
            Bug ID: 82437
          Assignee: idr at freedesktop.org
           Summary: [BDW] GPU hang when running
                    spec/glsl-1.50/execution/geometry/max-input-components
        QA Contact: intel-3d-bugs at lists.freedesktop.org
          Severity: major
    Classification: Unclassified
                OS: All
          Reporter: kenneth at whitecape.org
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/DRI/i965
           Product: Mesa

On Broadwell, running:

$ PIGLIT_PLATFORM=gbm shader_runner
tests/spec/glsl-1.50/execution/geometry/max-input-components.shader_test -auto

appears to cause GPU hangs, but only some of the time.  Other times, it passes.
 The error state has IPEHR at a PIPE_CONTROL, and the CS (command streamer) and
GS are busy.  Probably a hang while running the geometry shader.
