When booting with -a (or for other reasons) the kernel prompts for a root
file system device. It offers a list of devices available, but this list
is sometimes not correct.

In my case, a wi0 device fails to attach (for unrelated reasons):

wi0 at pci0 dev 0 function 0: can't map mem space

But still the kernel later offers to mount root via wi0:

root device:
use one of: aumac0 aumac1 wi0 ddb halt reboot
root device: aumac0

while the system, when up, does not list wi0 as an interface with ifconfig -a:

        address: 00:0e:56:00:02:2c
        media: Ethernet autoselect (10baseT)
        status: active
        inet netmask 0xffffff00 broadcast
aumac1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        address: 00:0e:56:00:12:2c
        media: Ethernet none (none)
lo0: flags=8009<UP,LOOPBACK,MULTICAST> mtu 33176
        inet netmask 0xff000000
