[Morten Clausen <morten.c@xxxxxxxxxx>]

I have to revice my comment from January 4th. The error is gone without
external display connected with 4.4.0 rc7 for me too, still occuring
with ext. display connected. I'm not sure what I was looking at, maybe
booted the wrong kernel, stupid me.

Since yesterday 4.4.0 rc8 is released, same behaviour without external
display connected, error is gone. I will check rc8 with external display
connected later this day when I'm at home.
