Comment(by greenfeld):

 Possible reproduction (or a magic dance which may be wrong, may take a few
 tries):

  1. Boot up an XO-1.5 11.2.0-22.
  2. When in Sugar, press the Power button once and wait until the system
 goes into suspend.
  3. Move your finger on a circle on the touchpad so the power light says
 on; stop after a few seconds.  Wait a few seconds.
  4. Move your finger on a circle again on the touchpad so the power light
 says on, and this time use your other hand to press the power button to
 wake up the XO after a few seconds of doing that.  Keep moving your finger
 on the touchpad while the screen wakes up, and see if the cursor starts
 jumping all over the place.

 I'm not certain if step 3 is really necessary but it may help, as I can
 reproduce this about 50% of the time this way.
