(Is that a > "big pointy hat"?:-) I'm having troubles with nfsroot on avr32 after updating my dev box to HEAD on May 31. I can see MNT RPC packet coming from the avr32 board and running mountd -d shows "mountd: mount successful" when the packet is received but no answer is transmitted, rpc is sent with udp. I can mount the same export from my osx workstation when using tcp. Arnar Mar Sig
