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
