+Possibly, but the documentation is wrong then.
+
+The nfs man page says that the line is ok, although "intr" and "nfs4"
+are deprecated (but should still be working).
+
+You can still try replacing "nfs4" with "nfs" (v4 is still tried first
+according to the man page), and removing "intr" (according to man page
+it has been ignored for years).
+
+On a related note, why do you use rsize=8192,wsize=8192? If for
+performance reasons, AFAIK and IIRC specifying them was useful only 5-10
+years ago or so, but now they actually could degrade performance as the
+default nowadays is "use as large values as possible", which is
+(currently) 1048576. So probably makes sense to remove them too.
