[Bug 856810] [NEW] Boot hangs at "Booting system without full network configuration..."

[Janne Snabb]

Public bug reported:

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.
