** Description changed:
This problem was introduced with Ubuntu 16.04 or rather with kernel 4.4;
I never had this problem on Ubuntu 14.04 and kernels from 3.x line.
Suspend works only twice in a row, sometimes three times, the next
attempt of suspending results in basically dead
I had too many problems with kernel 4.10 to be able to test this, so I
just let this report expire. Anyway, I kinda gave up with investigation.
One thing I discovered, and this is to people who may be reading this
and looking for a solution, was that suspend with 'sudo acpitool -s'
command was
[Expired for linux (Ubuntu) because there has been no activity for 60
days.]

I installed the latest 4.9 kernel (4.9.0-040900-generic #201612111631)
and tested both default open source nouveau driver and proprietary
nvidia-367 driver. Unfortunately problem still persists but now I can do
three successful suspends instead of two :))
I think my only way to get rid of this

Title:
Ubuntu 16.04 suspend
Marek Stasiak, to keep this relevant to upstream, one would want to
periodically check for, and test the latest mainline kernel (now 4.9) as
it is released.
Could you please advise?

Unfortunately the bug exists on the newest mainline kernel. It was hard
to test because it made my system very unstable (which is expected) and
I had trouble to get couple straight wake-ups from suspend to be able to
tell if it freezes like it did before. But it did freeze on third or
fourth

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.9 kernel[0].
If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.
If the mainline kernel does not fix
