dmesg for drm-tip: 2018y-04m-25d-17h-38m-40s UTC and drm.debug=14

Here you go Jani, I've just attached a new dmesg output with drm.debug=14 as
requested, tested on the current drm-tip from power on, with the external
screen detached at first, then plugged in.

In that scenario, I've let the external HP screen reboot once, then twice
before unplugging it to finally stop taking these logs.
