I still need test results from my kernel build, since that has what is
going to be in the next SRU kernel and if it's still broken then there's
something to be backported to core-drm (from v4.4..v4.6)

Title:
  Plugging HDMI screen in causes system hang

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have a 4K UHD laptop screen and am running Ubuntu Gnome 16.04 Beta1
  using 4.4.0-13-generic and the Nouveau drivers.

  If I plug in an external HDMI monitor (FHD) either into either HDMI
  port (there's one on the machine and there's one available via a usb
  3.1 extra adaptor) then the whole system hangs, completely
  unresponsive and needing a hard reboot. Before hanging the 2nd display
  gets an image as expected, but the laptop's screen flashes randomly,
  sometimes you see weird artifacts. Then the hang comes.
