Console has no name?

[Dimitry Andric]

Hi,

Somewhere between r198312 and r198702 I started getting this message
during boot, on a machine using serial console:

WARNING: console at 0xc093cea0 has no name

This is just before the copyright banner of the kernel.  Does anybody
have an idea what might cause this, before I start digging? :)

The machine has /boot.config with just "-P", and no console-related
entries in /boot/loader.conf.
