This patch suggests retrying after a short delay.  I've tested it and
while it does work, it does not ALWAYS work -- one time in 15 it has
failed me if I rapidly reboot.

I suppose we might need a:

~  maxtries = 5;
~  while (err == CMD_ERR && maxtries-- > 0) {
~    delay(...);
~    err = wd->atabus->...
~  }
