thanks for the response sir. sir i created nodes on the dev directory using the command mknode.Even after doing this i have problem.I do not know if there is any problem with nfs server.But as it is seen in the output on the minicom window sigseg signal occeurs then kernel panic happens.So how can this problem be solved.
