My kernel is custom one, with everything I could moved out to modules
(had to add "nodevice" entries for io and mem since they are in DEFAULTS
these days).  So I don't see how it can be related to MAC.


P.S.  Took me couple of hours to figure out that "uart" must be
compiled in, loading it via loader.conf does not quite work for serial
console.  :-(
