Okay.
Fairly straightforward SMP server-class system. P2B-DS, various
configurations. I've maybe a dozen of these and all exhibit it.
Consoles are all 9600 baud (i.e. default), and have ttyd0 enabled
in ttys.
A good percentage of the time (ranging all the way on up to 100%),
the console goes "nuts" right around the time it starts doing the=20
ifconfig's in netstart. This continues until the box is booted and
the getty runs on ttyd0, at which point all is fine. Alternatively,
if I go into single user mode and run /etc/netstart, I run the risk
of losing my console to this problem.
Now, it _appears_ as though something odd happens to the baud or parity
or whatever. However, kernel console messages (particularly ipfw)
continue to print with no problem.
Now, I "solved" (partially) this problem on some of my machines by
sticking a 'stty 9600 sane' in rc.network, but that doesn't really
solve the problem, because running other commands like ifconfig have
been known to toast the machine.
It looks like this:

Now, at that point normally it'd carry on like that until the login prompt

However, this box has the "stty sane" hack and actually reverts shortly
after that point.
