--- Comment #11 from Clayton Craft <clayton.a.craft at intel.com> ---
Also observed intermittent test failures for
KHR-GLES31.core.tessellation_shader.tessellation_control_to_tessellation_evaluation.gl_tessLevel
on HSW.

When compared to the HSW systems that did do not show this intermittent
failure, the main difference is that the failing systems have 1 DIMM installed
(8GB in channel A bank 0) and the non-failing systems have 2 DIMMs installed
(4GB each in channel A & B bank 0).

In this case, the failing systems are running kernel 4.9, and the non-failing
systems are running either 4.9 or 4.15.
