--- Comment #5 from Clinton Taylor <clinton.a.taylor at intel.com> ---
Many pipe underrun issues are caused by plane watermark programming in the i915
driver. Kernel 4.2 doesn't have many of the i915 CHV watermark fixes in later
kernels. 

Suggest backporting of CHV watermark fixes. Kernel 4.6 appears to have most of
the needed changes.
