Hello all,
I am having PPC7448 SBC running 2.6.16 Linux.
Ethernet device is TSI109. The board boots in ramdisk mode.
But NFS boot fails frequently,
First it will tell "NFS Server not responding" then "NFS SErver OK"
again it will tell "NFS Server not responding". Is this problem with driver or NFS server setting issue?
Thanks in advance.

network analyzer
use a network analyzer like wireshark to see the client requests and server responses
when i used wire shark i was
when i used wire shark i was able to see a lot of re transmissions, but it goes on re requesting and re transmitting. As if client has not got the packets from server
your finding
If you saw positive answers the client should expect (no error messages) from the server addressed to the client and the client didn't get the packets, you have at least answered your question: "Is this problem with driver or NFS server setting issue?"
Now you can focus on locating the problem on the client. Can you see, if the packets are received by the low level driver? I.e. is it a driver problem or are the packets thrown away later by the IP stack?
i gave some print statements
i gave some print statements and found that the packets arrived in etherenet driver and delivered to the "\net\core\dev.c". my kernel is 2.6.16. The packet reached at least upto netif_recieve_skb function.

Try changing the protocol by
Try changing the protocol by using
nfsroot=192.168.103.100:/target-ppcfs,proto=tcpor...,proto=udpinstead. Those are sensitive to different kinds of networking problems.
