Retested 4.13 + comment #2 patch.
plymouth (aka graphical boot) hangs the machine indeed.
when disabling rhgb gdm comes up just fine though, in both wayland and xorg mode. so apparently we have two issues here, and the patch fixes only one of them.
The plymouth hang appears to be pretty serious, the whole machine appears to be toast. I can't login over network to see what is going on, so it's not only the display which is f*cked up. Nothing written to the logs either. When enabling the serial console to see the logs plymouth skips the splash screen though, so the issue doesn't trigger any more. Hmm, I'm running out of ideas ...
I dropped the patch into the 4.12.12 update for Fedora kernels. The complaints I am seeing are screen strobing with this patch, it has been backed out for now. The plymouth issue is also a big one.
