I'd try to set

rootdev="disk8s1a"

in /boot/loader.conf in /dev/ad8s1a since boot loader and kernel seem to 
be read from there.

Before editing, please interrupt the boot sequence into command prompt 
mode and enter the command "lsdev" to have a look how the disks are 
enumerated by the boot loader.
