Yet I have double checked that, according /var/log/kern.log,

 - I booted this kernel:

Apr 18 13:18:29 david-desktop kernel: [ 0.000000] Linux version 4.15.0-041500rc1-generic (jsalisbury@kathleen) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)) #20180417120

 - I got black screen and the following message:

Apr 18 13:18:29 david-desktop kernel: [ 1.667490] [drm] Cannot find any crtc or sizes

And when I last booted this kernel:

Apr 17 06:17:34 david-desktop kernel: [ 0.000000] Linux version 4.15.0-041500rc2-generic (kernel@gloin) (gcc version 7.2.0 (Ubuntu 7.2.0-8ubuntu3)) #201712031230 SMP Sun Dec 3 17:32:03 UTC 2017

...it works just fine.
