Can't boot current on Minnowboard

[Renato Botelho]

As reported at pfSense ticket [1], we can't see console after booting
FreeBSD installer iso on Minnowboard.  This video [2] demonstrates the
problem.

Basically I can see all kernel messages but nothing from userland after
kernel finishes to load.

I would be glad to collect any kind of data you need to help tracking it
down.

Thanks!
