XO-4 B1 fails to boot
|Reported by:||wad||Owned by:||wad|

|Deployments affected:||Action Needed:||reproduce|
When an XO-4 B1 has been sitting unpowered for a long period of time, it sometimes doesn't boot. The visible symptom is that the screen powers on, but there is no boot chime and there is no XO icon drawn on the screen.
This is difficult to reproduce, as it always seems to boot fine the second time. I mainly discovered this when booting laptops from the factory for the first time.
The message printed on the serial port is the CForth banner through "releasing", then "Unimplemented package interface procedure". CForth eventually decides that OFW didn't start up and prints a 52 ("OFW seems not to have booted all the way").
