The same thing is happening on my laptop too with 16.04.1 : 470 G0/1948, BIOS
68IRF Ver. F.27 02/12/2014
After resume, the GPU seems to hang and needs a reset:
[10210.040529] [drm] stuck on render ring
[10210.041074] [drm] GPU HANG: ecode 7:0:0x85ffbff8, in chromium-browse
[19248], reason: Ring
I have the same problem with my Vivid installation. The laptop is a HP ProBook
470 G0.
When I close the lid, there are cases when it suspends, but in most of the
cases it doesn't.
The journalctl -b is attached, the journalctl -f shows this when the
suspend is ok:

another thing: the sudo systemctl suspend seems to be working...
