>Description:
When gettys are enabled to listen on ttyd* and one of the serial ports
is disabled in BIOS, the system crashes immediately after booting.
>How-To-Repeat:
Enable the following lines in /etc/ttys:
ttyd0 "/usr/libexec/getty std.9600" dialup on secure
ttyd1 "/usr/libexec/getty std.9600" dialup on secure
Reboot the machine and disable the first serial Port in
BIOS configuration. Boot the machine. Wait for crash.
>Fix:
Disable getty on ttyd or re-enable serial port in BIOS.
