Comment(by jnettlet):

 After another reboot the eMMC came back.  It is this block of code that
 busies out the eMMC.


 {{{
        \ XO-1.5 complete erasure of storage
        \ WARNING: practically irreversible
        open-nand
        " size" $call-nand d# 512 um/mod nip 0 swap
        " erase-blocks" $call-nand
        close-nand
 }}}

 after erase-blocks is called any further tests on int:0 result in the
 above behavior.
