When trying to reproduce the issue, I noticed that I could log into the GUI as created by the session manager (lightdm) if I left the cable in the onboard NIC. That means the system does go ahead when it can at least create one network connection other than lo (which is the default auto in my 15.04 configuration). If the NIC is not connected, the system will exhibit the symptoms as described above.

I attach both kernel logs (with and without a cable attached). More than happy to open a kernel bug report although that I do not think that this is solely a kernel issue. Please advise.

The last kernel version known to work is 3.17.8-031708; any later version up to 4.0.1 as installed from the Ubuntu kernel mainline archive fails with the symptoms described above. I also tried to reproduce this on version 4.1 but couldn't due to a GPL licensing issue (cf. https://github.com/longsleep/bcmwl-ubuntu/issues/2).
