Mike: I see you are using a PC, while I'm using an ARM board (with DT).
Are you using a serial console? If yes, what's the value of port->console
before and after the call to uart_console() that Rob's patch below removes?

Well, it's a bit larger than the average PC, it's a 64 core HP DL980,
and my console is its virtual serial port.

That's with the below from Jiri Slaby applied to quell the reboot time
explosion.

This alone is enough to fix things for you?

Yup.
