In my case, this behavior went away as soon as I tried the fix in comment #9 for bug #811441. For me, this was just a symptom that the system could not communicate with dbus.

Status in “lightdm” package in Ubuntu: Confirmed Status in “netcfg” package in Ubuntu: Confirmed Bug description: I installed Ubuntu 11.10 beta1 64bit on a new laptop. I rebooted and it came up nicely. After that I did "apt-get update" and "apt-get dist-upgrade" to get the most recent fixes and installed some additional software. Now I do not seem to be able to boot. Fist I see: Waiting for network configuration... Then I see: Waiting up to 60 more seconds for network configuration... And then it just hangs forever displaying the following: Booting system without full network configuration... Nothing happens after that, no matter how long I wait. However, I can switch to the console with CTRL-ALT-F1 and log in from there. The network is configured with DHCP and it works just fine from the console. I do not understand what the GUI boot display is waiting for. I installed the system using the alternate install CD to get LVM based partitions with full disk encryption. I noticed the bug #847782 and removed the "auto eth0" entry from my /etc/network/interfaces. Unfortunately that did not change anything, it still hangs forever.
