Giles, what your your fstab look like on the beaglebone black ? Also I'm
not 100% sure about this but for consistancy you should not use mmcargs,
but instead use netargs
This is what my own netargs line looks like:
> *netargs=setenv bootargs console=${console} ${optargs} root=/dev/nfs
>> nfsroot=${serverip}:${rootpath},vers=3 rw ip=${ipaddr}*

NFS version 3 works fine on Debian, perhaps Ubuntu is different ? I know
you've read other guides but perhaps reading my guild to double check what
you've done is complete. My guide:
http://www.embeddedhobbyist.com/debian-tips/beaglebone-black/beaglebone-black-nfs-root/
scroll down to *Configuring the NFS server *and read down to see if you
perhaps missed something. Also keep in mind that Although Ubuntu is based
on Debian, package names can be different, and not everything is done the
same way.
