UVM fault on Orange Pi PC plus

[Tom Trebisky <tom%mmto.org@localhost>]

Hello,

I recently tried running BSD 9.3 on an Orange Pi PC plus board I have here.
I used the dd command to write the supplied image as well as U-boot to 
an SD card,
but it is not running well.  It will often boot, but then take a fault 
while doing DHCP
or during some other part of system "setup" and I see the following.
I figured I should at least report it.
