Hi all, I ran into a weird problem when enabling serial console on the FreeBSD 7.0. Your help is really appreciated. I installed FreeBSD 7.0 amd64 (from the CD) on a Dell R200, and then enabled the serial console by adding the following to /boot/loader.conf hint.sio.0.flags="0x30" console="comconsole vidconsole" comconsole_speed="9600" boot_multicons="yes" And also replaced the following line on /etc/ttys ttyd0 "/usr/libexec/getty std.9600" dialup off secure with ttyd0 "/usr/libexec/getty std.9600" vt220 on secure. During rebooting, I found that the system hangs with the following messages and interrupt looks totally messed up " ... Trying to mount root from ufs:/dev/ad4s1a Manual root filesystem specification: <fstype>:<device> Mount <device> using filesystem <fstype> eg. ufs:da0s1a ? List valid disk boot devices <empty line> Abort manual input mountroot> ..." And to my surprise, if I keep rebooting again and again without doing any fixing, the problem comes and goes, which confused me. When the problem is not present, the serial console looks working normally. Can anyone help me with that? Thanks a lot.
