Comment 3 for bug 1794033

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
