Output of intel_watermark captured on BSW RVP after problem occurred

(In reply to comment #10)

Yes, the problem occurred while in steady state, at least from the user's
perspective.  I started the video playback, selected 1080p resolution, selected
full screen mode, and then just let it sit there.  I did not touch the keyboard
or the mouse while playback continued.

As you requested, here's the output of intel_watermark captured on the BSW RVP
after the problem occurred.  At the beginning of this particular test, I had
moved the cursor to the primary display and left it there untouched for the
duration of the test.
