Ubuntu 12.04 Not Loading After Updates – Initctl: Event Failed

After updating my Ubuntu installation I get a blank screen when try to load it. I have dual boot with Windows which works fine.

Going into recovery mode -> resume normal boot gives me the following error:

swapon: /dev/disk/by-uuid/18ed9859-1325-4121-96c8-2e696055454e: swapon failed: Device or resource busy
mountall: swapon /dev/disk/by-uuid/18ed9859-1325-4121-96c8-2e696055454e [3542] terminated with status 255

 * Starting AppArmor profiles                 [OK]
initctl: Event failed

Not sure what other info is helpful but these are some of my specs:

Intel Core i5-4430 3.00GHz
NVIDIA GeForce GTX 660 Ti
Linux 3.5.0-45-generic
Ubuntu 12.04

Things I've tried (from this question):

# went in to CLI with CTRL+ALT+F1:
sudo apt-get purge nvidia-current
sudo apt-get install nvidia-current
sudo reboot

# made sure all dependencies are ok:
sudo apt-get -f install

After doing the above I didn't get the swapon notices, but still go the AppArmor issue.

I don't know what else to check (or how to check) in order to debug this issue, any help is much appreciated.
