["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

niclas.kroon, the next step is to fully commit bisect from kernel 4.2 to
4.4 in order to identify the last good kernel commit, followed
immediately by the first bad one. This will allow for a more expedited
analysis of the root cause of your issue. Could you please do this
following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

After the offending commit (not kernel version) has been identified,
then please mark this report Status Confirmed.

Thank you for your understanding.

Title:
  Touchpad stops working randomly

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Touchpad stops working randomly, sometimes only scroll function stops
  working but mostly entire mouse freezes. Unable to move around the
  desktop. Cant find anything in dmesg-, xorg- or syslog- logs that
  seems to cause it. A reboot solves the problem temporarily but occures
  soon again so something is borked.
