This sounds like an inexcusable BUG if I understand correctly that one can not do a successful hibernate with ver. 17.04.

Some interesting points about 17.04 appear here (scroll down):

Confirms my approach, stick with LTS versions and I don't upgraded until after the first point release / update.
