I have suffered this behavior through several versions of Ubuntu, I believe since at least Precise.
For me changing smbd.conf start condition from :
start on (local-filesystems and net-device-up)
to:
start on (local-filesystems and net-device-up IFACE!=lo)
takes care of it, seems rather simple, I don't see why anyone would want to run SAMBA on lo.
