I have the same problem and it is reported as a Launchpad bug
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/727620

It occurs in let's say 7/8 boots, so if you patient enough you will be
able to start
To reboot safely, if it happens press CTRL+ALT+F1 to go into console and
then CTRL+ALT+DEL (otherwise it won't).

In order to not blacklist the driver you can disable modesetting at boot
in grub - just add
radeon.modeset=0
at the end of the linux line and it will boot fine.
