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).
