主要错误讯息如上

想问为何无法用NFS mount rootfs

我主机是eth1 ,ip=192.168.0.102

把cmdline发来看看，你有没有把rootfs目录设置为nfs共享目录？

我无言了!本来以为是ubuntu NFS有问题 特别换了两台电脑 还是不行,错误都一样

3)rootfs 位置
/home/mit/maxwit/rootfs

编译过程中都没问题,kernel,g-bios,rootfs都有做出来
然后直接选第13个选项Testing on QEMU

搞了好机天 失败

有人说kenel选项没开 不可能阿 我是用maxwit编的 config没改过
难道是编g-bios时的Build Bootloader (g-bios)没选对吗??我是选2440

错误跟这几篇很像
http://www.gossamer-threads.com/lists/linux/kernel/1134090
这篇好像有点感觉,要修改nfs code
