Comment:

 What's the status of this ticket ?

 It was believed that this might be due to operating the B0A (B0) silicon
 used in the A2 motherboards at too low of a main voltage.

 OFW was changed to operate the processor at a higher voltage, but due to
 complications in the check-in process it is unclear which versions earlier
 than Q7A15 actually operate at the higher temperature.   Please retest
 with Q7A15 if you haven't already verified that this was the problem.
