Disabling network manager seems to fix the problem.
in
/etc/NetworkManager/NetworkManager.conf
Add
[ifupdown]
ifupdown:managed=true

Then also configure your network in /etc/network/interfaces, and don't forget the dns-nameservers entry.

It seems like the bug is NetworkManager disabling the interface before going into standby. I have no idea to why this is done, but it certainly breaks nfs home directories.
