SamyGO

Weird, really.
Do you sure about downloaded correct version of Expansion Pack?
Some of those for C series...

You can also edit script by hand. If you can mount your NFS share by telnet,
Than you could remove whole scripts that responsible for loading kernel modules and just adding nfs mounting command will do the job.
Just change rcSGO file, clear it and add NFS mount command into it. This creates temporary solution.
Than you can dig deeper for diagnose problem. You can wait for final solution but I guess some wife's doesn't like waiting so much

Afaik telnet script could run other scripts too. Might be wrong. Forgot it already.
You can run SamyGO expansion pack from telnet/exlink connection too.
Than you can debug the process.
