I removed the debug print added the barrier, but that did not help. So, I was finally able to setup NFS using your replicated setup and I can't see the issue :( The only difference I have from yours is that I'm using TCP in NFS whilst you (I believe from the logs), use UDP. You do have flow control active right ? And your HW FIFO size is >= 4k ? --- Thanks, Jose Miguel Abreu
