Hello Everyone :

I'm failed when booting the board using NFS on AMCC PPC 405EP.
I think i have read the getting started guide carefully!
The tftp server and nfs server can works well. 
And the firewall was disabled, too.

My env was set as below:

Is this really an IBM/AMCC Bubinga board?

You are using not the SoC EMAC here. Why not? Is this Via chip connected to 
the PCI bus?

Again, not the SoC EMAC here.

This seems to be an error message from the network driver. I don't know this 
Via driver, so can't help here. But this seems to be the problem.
