Fair chance it will blow up and disable lockdep for pretty much every
console implementation out there, except 8250serial when used in

Maybe not the normal vga console, but I haven't tried on a machine that
has a monitor attached yet (they're usually not on remote power switches
and I'm too lazy to reach over and press reset).
