For the Mitac MIO A701 board, with a similar problem, I had :
- removed almost all drivers (except screen and USB for control)
- realized that the culprit was amongst drivers (which resumed in a loop in
that time, should be the same now)
- added some way to find which one failed (in my case, I chose morse code
through the buzzer to "speak" the device's name)
- found out the driver faulty code
- fixed it
- retried, cheered.
As soon as you reach a resumed screen, it becomes easier :)
That's a very tedious and long fight, good luck.
Cheers
