Ubuntu 16.04 LTS cannot suspend / fails on suspending

I have recently upgraded my desktop to Ubuntu 16.04. I had one problem with it before, which was that the Unity Launcher and status bar were missing. I solved this with this page. However, when I try to suspend my machine, the following occurs: The hard drive will save the last bits of data and will turn itself off. But the thing is: the computer itself is still turned on. This means I am stuck with no screen input, and it forces me to push the reset button on my computer case, as I can't take control of my pc anymore.

Can anyone help me with this?

I have the same problem, although it seems to be a bug rather some kind of misconfiguration, so there is nothing we can do about it right now. Let's hope the fix will be released soon. There is related bug report you can follow: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1566302

EDIT

In discussion from the link above, someone pointed out that the bug was fixed in kernel 4.4.8 and in fact it solves the problem for me. That means the issue was identified and we can expect an update in a few days.

If you're impatiant like me and you know what you're doing, you can install the new kernel by yourself from here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.8-wily/
