我的板子一直挂不上，一修改参数就会启动不起来系统，不知道怎么回事？
问题如下：
按照说明书想NFS方式mount主机，所有按照说明书上的办，但是出现下面问题：
NETDEV WATCHDOG: eth0: transmit timed out
NETDEV WATCHDOG: eth0: transmit timed out
NETDEV WATCHDOG: eth0: transmit timed out
NETDEV WATCHDOG: eth0: transmit timed out

root-NFS:sever returned error -5 while mounting /arysys2410/root
VFS:unable to root fs via NFS,trying floppy
VFS:cannot open root device "nfs" or unknown-block(2.0)
一系列的错误的，怎么解决啊？是不是还是网络不通畅造成的？怎么解决？谢谢。有的人说是主机的网络设置有问题，但是怎么来做才能设置正确呢？谢谢 |
