Below follows results of the tests, using the > 20150716-r285616 RPI-B image (built last night, propagating now). As I mentioned above, I have a card that will boot an old snapshot but refuses to boot on newer code. I have verified that the card will still boot the old snapshot, so I know the card is still good. That seems to indicate that something in the code has changed. Unfortunately, I am not enough of a programmer to be able to trace through anything that complex. -- Carl Johnson carlj@peak.org
