Title:
  Machine fails to resume from suspend

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  My machine (HP zbook 14 G2, http://store.hp.com/us/en/pdp/business-
  solutions/hp-zbook-14-g2-mobile-workstation-%28energy-star%29) fails
  to resume from suspend since kernel version 4.4.0-12. Version 4.4.0-10
  still works fine (I don't know about *-11).

  Below are the last log messages before machine suspended:
