For those of you just joining us, I have some new hardware that handles
ssh, scp, and samba all fine but NFS does not work. Put back in the old
NIC and all services are functional.
The onboard LAN (the bad one!) as seen from lspci -vvv:

I've filed a bug here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/503484
Basically I see this in dmesg on the buggy onboad LAN:
