Sorry. This morning is the first time I've seen this report, which was not To: or Cc'd to me. Since I don't have access to this kind of hardware, I will have to ask for your help to perform basic troubleshooting. Can we start by capturing the network traffic that occurs while you reproduce the problem? Use tshark or tcpdump on your NFS server, filter on the IP of the client, and send me (or the list) the raw pcap file. -- Chuck Lever -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
