hi srivatsan

thanks for the bug report. i believe i found the answer to #2, the rpc_message 
struct xdr_encode and xdr_decode were not initialized. please add these two 
lines of code to .../fs/nfsd4/callback.c

"callback.c" line 476 of 510 --93%-- col 2-9
        msg.rpc_proc = CB_COMPOUND;
        msg.rpc_argp = &cb->arg;
        msg.rpc_resp = &cb->res;
        msg.rpc_cred = NULL;
add >   msg.xdr_encode = NULL;
add >   msg.xdr_decode = NULL;
        rpc_call_setup(&cb->task, &msg, 0);

        cb->arg.cb_opnum = OP_CB_RECALL;

 i was able to 'vi' files which is a smoke test.

as far as the BAD DPUT errors - we need to chase them down. it's either the 
case that the corresponding dget did not go through the debug rig, or it's a 
real error.
