Thanks for working out what I meant. > Would you suggest to blacklist this module? Not in general, but that should work around the bug. That is effectively what we were doing before version 4.4~rc5-1~exp1 to avoid conflicts with older X drivers (while xserver-xorg-video-modesetting would override that blacklisting). Since we don't patch mgag200 any more, I don't understand why you are seeing a bug with the official kernel package and yet not with a custom kernel.
