 Right together with the power-on button being pressed, start bouncing on
 the

  * Esc key, or random keys across kb: keyboard mapping will be off
  * Volume up key: attempts to upgrade EC (even if version is current)
 and/or displays "cannot open audio". The audio problem - when it appears -
 stalls Linux boot at a point where we suspect it is starting up the codec.

 Seen with Q4B05 on XO-1.75 B1 units.

 We suspect OFW/SP/EC interaction issues.
