"Wire them down" in FreeBSD using loader.conf variables and this issue
will cease to be a problem.  Example is below, despite being for SATA
with AHCI -- really doesn't matter, just change the appropriate bits and
it should be fine for you.


# "Wire down" device names (ada[0-5]) to each individual port
# on the SATA/AHCI controller.  This ensures that if we reboot
# with a disk missing, the device names stay the same, and stay
# attached to the same SATA/AHCI controller.
