 The network is not down of course, the system is happily running with nfs 
 root from that
 server. Userland is older SUSE 10.0

Does Al's patch help in any way?

NFS mount gives ENETDOWN in -git15

I tried to mount another nfs mount on a system running with nfsroot.
But I get

# mount basil:/home /basil/home/
mount: Network is down

The network is not down of course, the system is happily running with nfs root 
from that
server. Userland is older SUSE 10.0
