Everything was attached in earlier bug report here:
https://bugs.freedesktop.org/show_bug.cgi?id=97918

I used drm.debug=0xe 

The "new" flickering was observed only once so I bet it was unrelated, please
ignore.

If using OpRegion has no downsides, then in my opinion the patch is ready and
issue fixed.
