Thank you very much for the help. Here is what I found after running 
ksymoops.

I am not a knowledgeabe kernel hacker, but here is my guess. It looks like
the code can be traced to /usr/src/linux/fs/nfsd/nfsxdr.c

---------------------------------------------------------------------
int
nfssvc_encode_attrstat(struct svc_rqst *rqstp, u32 *p,
					struct nfsd_attrstat *resp)
{
	if (!(p = encode_fattr(rqstp, p, resp->fh.fh_dentry->d_inode)))
		return 0;
	return xdr_ressize_check(rqstp, p);
}
-----------------------------------------------------------------

Either resp or resp->fh.fh_dentry is null.

I applied the raid0145-19990421 patch also.
