Comment(by dilinger):

 Replying to [comment:4 tvoverbeek]:
 > I have attached the output of dmesg on a joyride-2280 run.
 > The first part is on battery only, with battery almost empty.
 > The last part has mains power plugged in.
 > Note the extended EC traffic every 100 sec. At the end (while plugged
 in) the message sequence is much shorter.
 > Note also the nested touchpad calibration messages at e.g. 213 sec
 (short)
 > and 850 (long),  1476 (very long with lost synchronization)


 The resync thing looks like a race that was fixed here:

 As for the nested touchpad calibration messages; you need to stop using
 the touchpad when it's recalibrating for 2s, otherwise it will keep
 recalibrating.
