Touchscreen and hotkeys broken after suspend on HP Spectre x360

[Nicolae Istratii]

After boot all is working fine, but after suspend, touchscreen is no longer working and so are the hotkeys (brightness, volume etc.).
I am running the latest kernel (3.19.0-21-generic). The same thing happens with the latest 4.1 kernel.

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.

Once this bug is reported upstream, please add the tag: 'kernel-bug-reported-upstream'.

Strange that nobody else reported to be affected by the same bug yet.
I will have time to report upstream only after 20th July.

Nicolae Istratii, before reporting upstream could you please provide some more information first?

One thing that would be helpful is if you execute the following via a terminal:
apport-collect 1469280

Just got my hands back on the machine and after updates, reboot and suspend/unsuspend I can no longer replicate this issue (which is kind of sad, since I would prefer to play with it for some time...it's boring when everything just works).
Anyway, thank you for your attention and time!
