<pre>Dell XPS13 connected via Thunderbolt to Dell TB16 docking station as described

bz_status_NEEDINFO "
title="NEEDINFO - Dell XPS 13 and TB16 thunderbolt dock"
href="show_bug.cgi?id=103645">bug #103645</a> is showing a regression when running a 4.16.[1234] kernel.
Symptoms are a black power saved monitor connected to the DP output of TB16
after connecting the docking station. Keyboard connected via the docking
station still works, so Thunderbolt itself is working fine. The patch from bug
#104425 was tried out, but did not make any difference to the DP connected
monitor.
Kernel 4.15.x works just fine (or as fine it can work taking into account bug
#103645) with the DP monitor connected.</pre>
