Rick, Yeah sorry about the 3.14.x issues you're having. As I have not personally experimented with that, I could only speculate. However, there *is* a semi *kind of* documented "experience" with this sort of issue.
Ok, so I am going completely from memory, of reading a few post on these groups from months ago. But I seem to recall there being a kind of like "race condition" where a device may try to power up before the beaglebone black has all it's power lines up and "stable". In this case, you could try experimenting with a bash script that runs after everything else is up and completely running. Run level 5 or 6 I guess it would be with Debian ? Gerald could probably be more help here as far as letting us both know how the various voltages work on a soft versus hard boot.
