[Bug 1570820] Re: Suspend failure
Same effect here as you described (Samsung Ativbook 7 730U3E with
Intel/ATI graphic). Xubuntu 15.10 with all the updates worked. After
upgrading to 16.04 suspend stopped working.
Due to some issues with systemd during the upgrade I did a fresh install
of 16.04 Xubuntu but ran into the same suspend problem.
I hope you can fix this in the official Kernel as I'd like to stick to
the "original" an 16.04 is a LTS version.
I guess petersaints gave enough information (thanks for this!) - I just
want to push this with my vote :-)

Title:
Suspend failure
Status in linux package in Ubuntu:
Triaged
Bug description:
My laptop fails to suspend. The screen turns off, but the fans
continue to run (and it may actually get hotter). I wait and wait, and
nothing happens (the power indicator remains always on).
I tried suspending using the GUI, pressing the power button, closing
the lid, and even through the terminal with the "pm-suspend" command.
Nothing worked.
Suspend worked fine on Ubuntu 15.10 and older releases, but since I
upgraded to 16.04 I'm unable to put it to sleep. In fact, I had an
old 4.2 kernel installed from Wily. I booted into it and it suspended
and then resumed flawlessly, so it really seems to be a kernel related
bug.
I'll gladly perform any testing procedures that you may need to try to
identify what the problem may be.
I really hope that you are able to fix this soon, even if it will
probably after the final release.
