--- Comment #17 from perrantrevan at gmail.com ---
I believe I have problems as a result of this bug on the Intel Skull Canyon NUC
with Iris Pro 580 integrated graphics.

I had to turn off modesetting to complete installation of Arch Linux.

Now I can successfully boot into a DE with no problems. However, when I boot
into Kodi standalone or Retroarch in KMS/EGL mode the screen loses connection
just after the systemd version number appears. 

Very, very occasionally the screen doesn't go black for Retroarch. However, my
systemd retroarch.service fails (though I can manually start the systemd
service or /usr/bin/retroarch itself).

The same setup works with no problems on my laptop (Intel HD Graphics 4400).

I ssh'd into the running system when the screen was black: -
