dmesg.txt
Jumping here from https://bugzilla.kernel.org/show_bug.cgi?id=187571
I'm on HSW, and 4.9-rc5 is flooding dmesg with the subject matter. This did not
occur on 4.8-rc4 that I somehow ended up running without a reboot for 70 days
straight (it set a new `uptimed` record).
4.9 also surprised me by not recognizing HDMI connector unplugging anymore.
This hasn't occured for a long time and I've been on bleeding edge kernels here
since mid-3.x.
When I unplug the monitor, no display re-configurations happen. Suspend-resume
cycle helps restore connector state sanity, after wakeup the extra display is
gone (verified in Gnome Display Settings).
