Have you tried using > wireshark to see if any NFS traffic is arriving at the server from the > client? Yes, the server gets no packets from the client between linux 2.6.37 and 3.1. In linux <= 2.6.36 it also doesn't get packets from client to RPC port 10003 (not even ARP packets) but then the kernel tries 10005. This works (the server gets ARP, then SUNRPC packets and the client can mount NFSROOT). > Have you tried using the 'mountproto=tcp' option? Now yes. There were no ARP or SUNRPC packets. That's the result of linux-3.1 with 'mountproto=tcp': --- {0} ok boot net root=/dev/nfs rw nfsroot=137.226.167.241:/srv/nfs/cluster2,mountproto=tcp ip=137.226.167.242:::255.255.255.224::eth0:off nfsrootdebug Boot device: /pci@0/pci@0/pci@1/pci@0/pci@2/network@0?
