Hello misc,
I am just in the process of moving one of my servers from i386 to amd64.
My webhoster provides me with a serial console over a ssh connection
with the speed set to 57600 baud. The following boot.conf works for the
bootloader:
set tty com0
stty com0 57600
But after the -current kernel is loaded and the main func is executed
the serial speed is reset to 9600 baud, which gives me output like this:
`````````````````````
com0: 57600 baud
boot>
booting hd0a:/bsd: 4415664+1071036+748152+0+557208
[80+390168+243800]=0xb16058
entry point at 0x1001e0 [7205c766, 34000004, 24448b12, cba0a304]
m```````````````
(The last line starts right behind the closing bracket in the line
below, my mailer will break the line, so I can't show that in the right
way here).
The com_speed variable is set to 57600 at the point where the kernel is
started. Those accented 'a's show up if I set the console speed to 9600
and have any output on the console, so I am pretty sure that the com
port is reset to 9600 baud after the kernel starts.
Is there any way to get a readable output on the serial console at 57600
baud? I can change /etc/rc to set the console back to 57600 but that
won't help if I got a kernel problem or if I would like to use the -s
boot option. In fact I am expiriencing exactly this problem at the
moment...
dmesg is below is from an install kernel for i386 4.2-stable. The
i386-4.2 kernel does not show the behaviour described above.
Kind regards,
Markus
