No - the issue was not resolved. We looked at it, but could not
figure out what the SD card (and/or controller) did not like about the
seabios initialization sequence. The sd card would stop responding
and it wasn't clear what seabios was doing different from linux (which
apparently works fine on the same hardware).
As Paul mentions, if you'd like us to look at this further, please
include the debug logs of a session. It's possible additional tests
on new hardware will reveal the issue.
