--- Comment #3 from Radhakrishna Sripada <radhakrishna.sripada at intel.com> ---
I connected a 1920x1080 eDp panel on to skylake RVP. Running drm-intel-nightly:
2015y-12m-02d-16h-11m-34s DMC version 23 - chromium os, I was able to see
flickers on eDp when I hover the mouse. The screen goes blank and settles back
after 3 seconds or after hitting space bar. 

I donot see the issue when I connect 1366x768 eDp. 
I observed the issue when I was backporting atomic watermark updates onto 3.18
kernel. I was unable to revert the commit 024c904 on top of the
drm-intel-nightly branch. I narrowed down by comparing the 024c904 commit and
its parent commit.

Without the commit 024c904 I see flicker on eDp when I connect an external
monitor over HDMI/DP irrespective of the edp panel's resolution.
