Here is a summary of the information that I can provide:
1. Which part of the process does the issue occur with, the suspend to ram, or
resuming from?
Please advise how you suspended specifically. For example:
Issue occurs when resuming.
I have suspended using the following methods: i) Click GUI menu item
"Suspend" and
ii) Briefly press the power button
2. Please advise how you resumed specifically.
I have resumed by pressing space or the power button. The commands below were
run after
attempting to resume by pressing the power button.
3.-10. [various commands] + Please attach to your report the resume
trace mentioned below.
Commands run but I'm getting an error running the resume trace following the
"resume-trace
debugging procedure for finding buggy drivers" method:
sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend"
sh: 1: cannot create /sys/power/pm_trace: Permission denied
Please advice.
11. Please provide the output of the following terminal command:
cat /sys/kernel/debug/suspend_stats
Done. Please see my reply #10 above.
12. If you have a graphics related issue after resume (corruption,
display blank, etc.) please SSH into your machine and capture both
/var/log/Xorg.0.log and /var/log/Xorg.0.log.old. Please attach each
separately.
I have this issue but SSH connection was not possible during the blank screen
after resume.
Tried both WLAN and fixed connection. Apparently networking is down after
resume. Attached
both log files nevertheless. See the attachments in replies #10 and #11 below
Please help me solve the "Permission denied" error to enable tracing in steps
3.-10. Also, please clarify if you need a separate resume trace from every step
or just one trace after completing all of the steps 3-10.

Title:
[HP 15-r085no Notebook PC (ENERGY STAR)] Suspend/resume freezes
Status in linux package in Ubuntu:
Confirmed
Bug description:
My HP notebook won't wake from suspend with 16.04 LTS, waited for the
latest 4.4.0-36 kernel update before reporting this bug. Computer goes
to suspend, but attempts to wake it up just start the fan (and HDD)
while the display remains black.
Also tested this with the mainline upstream kernel
4.8.0-040800rc3-generic. With this version there was different
behaviour but still a bug: the display woke up but Ubuntu was very
unstable, did not connect to Wifi and the GUI froze very soon after
resume.
