git bisect log
Fedora has gotten several reports of 100% failure to boot while docked (see
<a href="https://bugzilla.redhat.com/show_bug.cgi?id=1549042">https://bugzilla.redhat.com/show_bug.cgi?id=1549042</a> for example) as a
regression between kernel versions 4.14 and 4.15. I bisected and came up with
commit 5ea2355a100a3c6304901d058aee06d3a6be69bc (refs/bisect/bad)

drm/i915/mst: Use MST sideband message transactions for dpms control
Use the POWER_DOWN_PHY and POWER_UP_PHY sideband message transactions to
set power states for downstream sinks. Apart from giving us the ability
to set power state for individual sinks, this fixes the below test for
me.
$ xrandr --display :0 --output DP-2-2-8 --off
$ xrandr --display :0 --output DP-2-2-1 --off
$ xrandr --display :0 --output DP-2-2-8 --auto #Black screen
$ xrandr --display :0 --output DP-2-2-1 --auto
v2: Modify and document the dpms and port disable order (Ville)
Add comment explaining is_mst = !crtc_state equivalence(Ville, Maarten)
v3 by Jani: rebase

I can track down other reporters but my setup was Lenovo T470s with dock to
HDMI monitor
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620 (rev 02)
Happy to provide more information and point other reporters here.</pre>
