Hi, I believe this MFC commit: http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/boot/i386/libi386/comconsole.c?rev=1.10.10.1&content-type=text/x-cvsweb-markup broke the speed-setting of the serial console at boot time, for RELENG_6.
At least for me, it doesn't set the speed to 115200 (as specified in
make.conf) anymore, it always stays at 9600, even when I put
comconsole_speed=115200 in loader.conf.
I noticed this, when I upgraded from 6.0-STABLE built around december
last year, to 6.1-PRERELEASE from last week. The serial console on this
particular machine had been working flawlessly for years now...
There's a new comment added by the commit in this file that says:
/*
* Assume that the speed was set by an earlier boot loader if
* comconsole is already the preferred console.
*/
whereas in the previous version it was set (hardcoded) to COMSPEED,
which in its turn came from BOOT_COMCONSOLE_SPEED in
boot/i386/libi386/Makefile.
Anyone know of a way to restore the old behaviour? I'll experiment here
with reverting the comconsole.c file to the previous version, to see if
that helps, but a permanent solution would be better. :)
Cheers,
Dimitry
