 On an XO-1.75 A3 (#30), running cl2-4.0.0.11 and q4a13n firmware,  an fs-
 update hung.  The USB key being used has been reliable.  os9.zd was being
 installed.

 No error message was printed, it just stoped incrementing through the
 blocks after around block 12000 or so.

 A reboot and immediate retry succeeded.  This motherboard was fresh "out
 of the box", but has since completed 2GB of writes in SD test while
 simultaneously runnin memtest so it isn't obvously bad hardware.

 This is possibly related to a problem repoerted by Quanta, where the eMMC
 hung when being written to on ome units.  Thermal was blamed, and this
 unit is missing a heat shield.
