Not with that particular syntax. It just produces a message about "bad definition". HDMI
output ends with the kernel probe, resuming with a login prompt.
The serial console reports in part:

------end serial console output--------
I included the lock order reversal messages as a curiosity; don't recall seeing them before.
It's worth noting in passing that the /usr/src/sys/arm/conf/RPI2 config file used in this
setup contains the lines:
# Comment following lines for boot console on serial port
device vt
device kbdmux
device ukbd
The machine _has_ a serial console, and only a serial console, despite the lines not being commented.
Are the comment instructions backwards?
Thanks for reading!
