--- Comment #22 from Dominik 'Rathann' Mierzejewski <dominik at greysector.net> ---
Looks like I have an affected machine as well. I encountered this when bringing
an old installation (F26) up to date.

dmesg from 4.17.14-102.fc27.x86_64:

4.14.x works fine like in Sérgio's case. Mine is also a single-screen setup
(LVDS-1) with no external outputs connected. There are no errors in Xorg log.

I believe this is a different bug than
https://bugzilla.redhat.com/show_bug.cgi?id=1547037 and patch
https://github.com/skeggsb/nouveau/pull/1/files did not fix this.

Sérgio, are you sure the above patch fixes this for you?
