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.
