--- Comment #1 from Dennis Clarke <dclarke at blastwave.org> ---

It was seen that the physical MAC addresses of the bge0 and bge1
interfaces were exchanged in the output from 'ifconfig -a' and thus the
flat device tree option usefdt=1 may be the cause. 

Once this was seen it was trivial to bring up both interfaces and to
assign the correct ip to bge1 and then stop start ntpd and sshd etc.
