When it does work, I do see the ethernet NIC lights come on immediately and the board starts responding to ping 30-60 seconds later. When it doesn't work, I get no NIC lights. I think that means I have a hardware problem?
If it makes a difference, I'm running with the 12v/5A PSU.
It also seems to matter how long the power is off - I haven't checked systematically, but auto-start seems to be more reliable if the board is unplugged for more than a minute or so. Does that make sense?
It might be because short power break doesn't lower PSU output to zero - there is some residual voltage so power resumption causes, say, a 9v pulse on power restore.
A longer power break makers the output fall to zero so, power resumption creates the full 12v rise.
Possibly?
