INIT: Id "con" respawning too fast: disabled for 5 minutes

linux内核启动后出现：

BusyBox v1.18.4 (2011-03-22 14:01:42 CST) multi-call binary.

Usage: getty [OPTIONS] BAUD_RATE TTY [TERMTYPE]

Open a tty, prompt for a login name, then invoke /bin/login

Options:
        -h              Enable hardware (RTS/CTS) flow control
        -i              Don't display /etc/issue before running login
        -L              Local line, don't do carrier detect
        -m              Get baud rate from modem's CONNECT status message
        -w              Wait for a CR or LF before sending /etc/issue
        -n              Don't prompt the user for a login name
        -f ISSUE_FILE   Display ISSUE_FILE instead of /etc/issue
        -l LOGIN        Invoke LOGIN instead of /bin/login
        -t SEC          Terminate after SEC if no username is read
        -I INITSTR      Send INITSTR before anything else
        -H HOST         Log HOST into the utmp file as the hostname

INIT: Id "con" respawning too fast: disabled for 5 minutes

原因：不能获得此时console的baudrate，所以，不断打印重复信息，导致init进程将其disable for 5min。

解决：

/etc/inittab中，

将

con:2345:respawn:/sbin/getty console

改为

con:2345:respawn:/sbin/getty 115200 console
