1.启动参数如下：

bootargs=root=/dev/nfs nfsroot=192.168.1.8:/opt/wheezy_fs ip=192.168.1.9:192.168.1.8:192.168.1.1:255.255.255.0::eth0:on init=/bin/bash console=ttySAC0,115200

1.1错误信息如下:

bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell

2.修改启动参数:

bootargs=root=/dev/nfs nfsroot=192.168.1.8:/opt/wheezy_fs ip=192.168.1.9:192.168.1.8:192.168.1.1:255.255.255.0::eth0:on init=/sbin/init console=ttySAC0,115200

3.再次出现新的错误:

udevd[178]:unable to ctrl connection :function not implemented
