I'm not having any luck getting my 115200 baud serial console back.   
The machine was upgraded from 5.4-STABLE to 6.1-PRE last week, and  
again over the weekend.  I did the following:

make buildworld and buildkernel with BOOT_COMCONSOLE_SPEED=115200 in / 
etc/make.conf, options CONSPEED=115200 in the kernel config.

make installkernel, reboot, yada yada yada, installworld,.. then  
boot0cfg -B aacd0 to update the boot blocks.

Now, at this point I expected to have a 115200 console on the next  
boot.  Nope. Got 9600 baud again.

The other side-effect is now I get this stupid "Boot F1 for DOS and  
F2 for FreeBSD" menu which defaults to DOS (which is the Dell utility  
partition).  How do I get back to the original boot style where it  
just boots freebsd without any menu?


So I updated my /boot.config to read:

  -Dh -S115200

now on boot, the boot0 drops to the prompt and makes me type in "/ 
boot/loader" to continue the process.  It is as if it forgot what  
file to load, and ignores the -S option anyhow, because I still end  
up with a 9600 baud console.

I ran out of time to try setting the speed in /boot/loader.conf but  
I'm not expecting any miracles.
