            Bug ID: 104778
           Summary: intermittent unit test crashes since mesa 17.2
           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
            Blocks: 104757

Mesa CI reports a low error rate (2/700k), however the number of intermittent
failures is consistently nonzero.  This is worse than our historical results.

The rarity of the failures makes it difficult to pinpoint the regression,
however there are several repeating errors:

i965: Failed to submit batchbuffer: Bad address
    piglit.spec.!opengl 1_1.copypixels-draw-sync  ivb
    piglit.spec.!opengl 1_3.gl-1_3-texture-env   snb


intel_batchbuffer.c:937: submit_batch: Assertion `entry->handle ==
batch->batch.bo->gem_handle' failed.
    piglit.spec.!opengl 1_3.gl-1_3-texture-env.bdwm64
    piglit.shaders.glsl-fs-raytrace-bug27060 skl

HSW tesselation failures
