For me it never took this long before.  The time it takes is really
exceptional; the system is unusable for about 5 minutes and error
messages appear on Gnome settings timing out.  I'm not using DHCP either
but even if I was, this can't be normal cannit..?    On laptops it
happens all the time that you're on a different network and need to
switch; this switching now easily takes 5 minutes before I can even get
the Network settings panel opened.

It says:

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1

          RX bytes:78790 (76.9 KiB)  TX bytes:78790 (76.9 KiB)

However this is now after I got my network settings switched to my
company LAN. I will try it again when booting up without network.

Thanks!!! All very helpful, I'll check it out.
