Doug, you added the tag 'kernel-fixed-upstream' but I don't think we
have hard evidence of that at this point. Was your tagging based only
on Viktor's reports that it hasn't happened (yet) on a 4.6 kernel, or is
there more information elsewhere?
Viktor, your result with 4.6 is promising! However, since this problem
is known to "come and go" it is also possible that code has just moved
around such that its just not manifesting in your current 4.6 kernel
build you currently (but could reappear in some future build of 4.6).
I do see one potentially interesting fix in 4.6 (50220de HID: core:
prevent out-of-bound reading). I'm going to produce a test kernel with
just that fix backported on top of Xenial 4.4.0-22.40 (which I've seen
manifest the problem), and will post that here for further testing.

Title:
Key 5 automatically pressed on some Logitech wireless keyboards

Bug description:
I have a K520 Logitech keyboard and sometimes something starts to keep
pressing key 5.
It mostly happens when I leave the computer alone for some time, but
sometimes also just during regular usage.
It seems that this is a Linux specific issue as no one is complaining
about this issue under Windows, but a couple of people are complaining
for different versions of Ubuntu.
It is always 5 and WladyXX3740 claims on the Logitech forum that:
"happens on Ubuntu 15.10 and 16.04, does not happen on Ubuntu 15.04, probably
kernel related."
Here is where most of the people are complaining:
https://forums.logitech.com/t5/Keyboards-and-Keyboard-Mice/Ubuntu-15-10-and-K520-key-5-automatically-pressed-resulting-in/td-p/1488639
I discovered that this is related to my Logitech keyboard by running this
command:
xinput test-xi2 --root
Here is the device list:
