>Description:
	

For years I've been building my systems with a serial console running at
115200 baud.

Now, with 6.1-PRE, it seems that the console is wired to 9600 baud despite the
following settings:

make.conf:
BOOT_COMCONSOLE_SPEED=115200

kernel:
options		CONSPEED=115200	# Speed for serial console

and in /etc/ttys:
ttyd0	"/usr/libexec/getty std.115200"	dialup	on  secure

/boot.config has "-Dh"

The serial port insists on running at 9600 baud during boot/shutdown and even
getty has its speed overridden to 9600 baud so login is at the slower speed
too.

>How-To-Repeat:
	

upgrade 5.4 system to 6.1-PRE via source with above settings.  serial console
insists on being 9600 baud.

>Fix:

	

I wish I knew.  It works as expected with the above settings since version 4.1
through version 6.0-REL-p4.
