Ubuntu :: Login Prompt - Virtual Terminals Not Working?

Usually I get a login prompt on Ctrl+Alt+F[1-6], but now I just see a blinking cursor in all of them, along with some boot messages in the first virtual terminal.

Code:
fsck from util-linux-ng 2.6
init: bootchart main process (462) terminated with status 2
init: bootchart post-stop process (474) terminated with status 127
/dev/sda2: clean, (integer)/(integer) files, (integer)/(integer) blocks
init: ureadahead-other main process (870) terminated with status 4

What's even weirder about this is that I uninstalled bootchart a few months ago. Whether that's related or not is beyond me, but the virtual terminals did stop working somewhere around that time. I solved this by reverting to my original /etc/network/interfaces file. Without the loopback "lo" device, the runlevel was never set, and virtual terminals never loaded.

This should be somewhere in the interfaces file:
Code:
auto lo
iface lo inet loopback
