I'm looking into the syslogd capabilities at the moment, it might be

I've tried following the serial console setup you've pointed, but when I
added the 'console="comconsole"' to loader.conf the OS hanged during
boot time, had to re-install the system.
I'm currently porting Mellanox ethernet driver, InfiniBand will be
probably next. Mail me outside this list if you're interested in
InfiniBand.
The OS probably didnt hang, you told it to send all its output to
comconsole (ie serial port) and not display anything. This might look as
though it has hung. Try (in /boot/loader.conf):
boot_multicons="YES"
console="vidconsole,comconsole"
to output to both of them. Also, set the correct tty on your serial
console with something like (in /etc/ttys):
ttyd0 "/usr/libexec/getty std.9600" vt100 off secure
There will be a ttyd0 line already.
All of this is in the various handbooks.
Cheers
Tom
