 Configuration: install os16, set aggressive, start runin.

 Problem: after a few minutes the system hangs during a suspend or resume,
 there is no response to keyboard, but the power button responds to a long
 press.  The startup sound no longer occurs.  "test /audio" yields no
 audio.  These two symptoms are cleared by removing the external DC power
 and battery.

 Reproduces so far only on an XO-1.5 C1 unit here, SHC9500002A.  The heat
 spreader test passes, rise is 5 degrees C.
