Hello!

> Deadlock - in exactly the same way as with the xprt code...

Soooory! Delete from the picture all except for containing QDIO:


(Call QDIO bottom half code)
spin_lock(&QDIO_lock);
                                                 <QDIO hard interrupt>
                                                       ->spin_lock(&QDIO_lock)
                                                              (spins...)

with the same result. No help of nfs is required. :-)

So, you have drawn wrong picture.
