In this case/at this point I wanted dmesg output so I could provide you
working /boot/loader.conf lines for your configuration, with regards to
"wiring down" device names.  If you mess with controllers (e.g. disable
one in the BIOS), this may break.  Here you go:

# "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.

# ada[01]     = JMicron JMB363
# ada[234567] = Intel ICH10
