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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1488719 Title: dmesg shows "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!"
