nfs root problem - empty directories

Hi,

We have been using NFS as root filesystem on the IBM PowerPC 440GP
evaluation board (I think it's not really related, but just for the
scope). We also have Busybox.

We have a rcS that is executed by the busybox's init.
Sometimes the script executes and stops in the middle of its
execution.
We got some "NFS: readdir reply truncated!" errors some other times.
Also, when we list the files in the /etc/init.d directory, it seems
empty (although - it is full on the server)..

Does anybody have any idea?

Thanks,
Elad Ben-Israel.
