XO-1.75 A3 fails to boot OFW

On two occasions now, my 1.75 A3 prototype (#39, fully packaged into a laptop) has failed to boot from a cold start.
It is running OFW Q4A13h, and the EC firmware built by Mitch on 5/19 which staggers the SD card turn-ons.
The first time, the message printed on the screen was: "Data Abort", followed by the ok prompt (nothing else was printed). The second time, the message printed was "Software Interrupt<cr>ok Software Interrupt<cr>ok" (where <cr> is a carriage return).
In both cases power cycling the laptop resulted in a complete boot. It is impossible to duplicate without letting the laptop sit powered down for many minutes.
One postulate is that this is due to a switching transient on one of the power rails, as devices are first turned on by OFW.
(Can we please get a 1.75-A3 hardware selection added to "Version" ?)
