When i am capturing packet at NFS server I can see NFS packet coming in and out from the etho.

I have enabled the NFS support option as well as roootfs over nfs option in the Network file system option also BOOTP support kernel level auto configuration.

Using following Boot line parameter:

bootargs=root=/dev/nfs rw ip=192.168.202.20:192.168.202.22:192.168.202.1:255.255.255.0::eth0 nfsroot=192.168.202.22:/vijay/vkfs,rsize=1024,wsize=1024,timeo=20,retrans=10 mem=32M nofpu


When I debugged the code I found that it is getting hanged after the call of run_init_process("sbin/init"); in the file init/main.c file.

Is any thing else need to be configured which I am missing or something else is required.

Any suggestion ??

Thanks in advance ....

Regards
Vijay
