Comment 12 for bug 856810

Hi Janne, can you attach your /etc/network/interfaces file? If you have a hardware interface defined there as dhcp, but not always plugged in, the system will wait an extra 2 minutes to boot. As kvark points out, those are the relevant bugs that have been dealt with since introducing that change.

However, I'm fairly certain this is a red herring, as the last message is the one thing printed before the failsafe boot continues. Essentially, at that point, the system is virtually guaranteed to enter runlevel 2, which should result in lightdm starting as long as dbus has been started, and a graphics device has been initialized.

If somebody affected can boot with '--verbose nomodeset' added to the kernel command line (edit it during the grub menu) and 'quiet' removed, and then try looking on tty1 (ctrl-alt-f1) and 7 (ctrl-alt-f7) for some log output, that may be helpful in debugging this.
