Comment(by wmb at firmworks.com):

 I still have not managed to reproduce the Data Abort.  The machine I am
 testing - XO-4 B1 #7B - has done 17879 reboots without a Data Abort.
 Every now and then - perhaps one in 5000 reboots - it fails to see the USB
 stick and tries to boot Linux from the eMMC.  I guess it's possible that's
 a different manifestation of the same underlying problem, but it's not
 clear.

 The last test run was doing the full SPI-reflash of alternating images.

 I'm going to try running the reboot script from eMMC, thus removing USB
 from the mix.
