hi all,
my 8270 board (2.4.26, u-boot 1.0.1, ELDK3.0) can't boot over NFS.
The messages are ..

Most time it hangs on "INIT: version 2.84 booting"
Any ideas ??
Why the "rootpath" isnt passed to the kernel? Are the domain and nis-domain necessary for booting ?? With an initrd it works fine and i can ping the target and reverse.
Thanks for your ideas
Marco
