In addition to my post #78: same kernel, so same problem persists in 18.04 alpha (Bionic Beaver). Installing 4.14.13-041413 (and hibernate after a new reboot) as suggested above solved this problem for me.
I would strongly suggest that the Bionic developer team will consider to include this version in the release.
