Please find my replies below:
1. I'm seeing various issues after suspend / resume. With the latest
kernel builds, typical is that the GUI freezes shortly after resume.
Often resume does not complete at all and I only see black screen with a
cursor / underscore in the top left corner. I would be
Two questions:
1. Comment #16 is the issue now?
2. What release do you use now? Do you still use Trusty?

Tested with mainline kernel 4.9-rc3 and the bug still exists.

$ sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend"

Tested with 4.8-rc8. It was possible to login after the resume and use
the GUI in offline mode for several minutes. Two observations: 1) Wifi
and networking are not available after resume, 2) Ubuntu hangs when
selecting "Shut down" from the menu.
Could this issue be related to the RT3290 wireless
Arto Makkonen, not sure on why all of a sudden one gets a permission
denied. The article may need to be updated.
Despite this, to keep this relevant to upstream, one would want to test
the latest mainline kernel (now 4.8-rc5) as it is released.
Could you please advise?

Thanks for letting me know that a new bios version is available (oddly
the HP support site did not show any available bios versions for my
laptop with 'Windows 10' setting, but F39 and F18 were available by
setting OS to 'Windows 8.1').

shortly after.
