I am not so sure I followed your tests. Could you confirm and complete that: - upstream + your patch: keyboard works, 2 finger scroll doesn't but it hangs after an hour or so, and keys are repeated from time to time - hid for-next branch: keyboard works, 2 finger scroll too, but it hangs after an hour or so, and keys are repeated from time to time - vanilla kernel 4.9-rc6: no hangs, but what is the status of the keyboard/touchpad? I have the impression that when the keyboard is disabled (plain v4.9-rc6) you don't experience hangs. So if that is the case, then maybe the keyboard is somewhat messing up the system. I don't know if that would be counted as a regression :/ Unless the keyboard is already working with a plain v4.9-rc6 but just doesn't after suspend/resume...
