--- Comment #4 from Ankit <ankit.k.nautiyal at intel.com> ---
I reproduced the issue on ICL with eDP.
I could see the subtests with YUV Pixel formats were failing, due to CRC
Mismatch.

The CRC for the given flip, was different for each run, and not matching with
the reference CRC.
So I recreated that flip, and checked the CRC for Plane index 0, 1 and 2.
Looks like initially the CRC is unstable, but becomes stable soon after.

Which lead me to add a delay between the commit and CRC capture, to check if
that solves the problem.

With this the CRC does match for Plane index 0, 1, and 2, but for Plane-index
3, the CRC again does not match even after a substantial delay.

Debug in progress.
