Dear Maintainer,


   * What led up to the situation?
Sometimes randomly and everytime after suspend, touchpad stops working on
ThinkPad-Helix with the selected kernel.
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
adding the following kernel parameter seems to solve the problem:
psmouse.synaptics_intertouch=0
   * What was the outcome of this action?
touchpad stops working.
dmsesg output:  rmi4_physical rmi4-00: Failed to read irqs, code=-6
   * What outcome did you expect instead?
working touchpad like in Debian 9 / Kernel 4.9
