So, checking /boot/device.hints shows:
hint.uart.0.at="isa"
hint.uart.0.port="0x3F8"
hint.uart.0.flags="0x10"
hint.uart.0.irq="4"
hint.uart.1.at="isa"
hint.uart.1.port="0x2F8"
hint.uart.1.irq="3"

show from loader:
OK show
LINES=24
boot_serial=1
console=userboot
currdev=disk0p3:
interpret=OK
kernelname=/boot/kernel/kernel
loaddev=disk0p3:
prompt=${interpret}
smbios.bios.vendor=BHYVE
Any ideas?
Oh, I did verify that uart0 is functional by logging into the system
and doing: echo foobar > /dev/cuau0
So, it's not like the console is not working, it's clearly a problem w/
the kernel deciding to use it as console..
