Hi Joe,

Indeed, you are right - I have now fixed the problem! Thanks very much for
your help!

I was previously using a serial console to boot the machine, whereas now I
have an IP KVM.

The lines I commented out in my /boot/loader.conf to fix this were:
boot_multicons="YES"
boot_serial="YES"
comconsole_speed="115200"
console="comconsole,vidconsole"

I would have thought that the boot should still complete regardless of
whether the serial console is connected or not?

Regards,
Ben
