--- Comment #28 from Jerome <an.inbox at free.fr> ---
Thanks for the info John, but it doesn't apply to my case unfortunately: I
don't have the "hibernation" package installed. With systemd there is no need
for it, and then whether you close the lid of use a power button or "systemctl
hibernate" it's the same kernel interface (/sys/power) that is used. I tried
all variants before and get hangs-up on my laptop in all cases.

I installed the "hibernate" package to have a look (it also hangs on my laptop
BTW), and the suspend/resume sequence is slightly different than with just
systemd: hibernate displays the state save/restore progress in text mode, and
when restoring the graphic mode I have a transient "screen filled with random
noise" state that doesn't happen with systemd only. So there is some
difference, but not enough to change the result on my laptop...

While I'm at it, hang-up on resume still happens with Intel nightly kernel
4.6.0-rc6 as follows:
