我尝试在设备上加载嵌入的Linux。
内核命令行：
setenv bootcmd 'nfs 10.0.0.1:/home/master/rootfs3/boot/uImage;bootm;'
setenv bootargs console=ttyTX0,57600n8 root=/dev/nfs rw nfsroot=10.0.0.1:/home/master/rootfs3 ip=dhcp init=/sbin/init
系统加载失败：

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)
Server returned error -5-这是什么意思，我在哪里知道这个错误？
1.防火墙在我的fedora 18SystemCtl停止防火墙SystemCtl禁用FireWalld
2.可见的selinuxvi/etc/selinux/config
- 注释selinux =执行 - 添加＃selinux =禁用
重新启动您的Linux。
