Comment 38 for bug 554737

Ah, so if you can't login /forcefsck is not removed - that's really odd.

So to get rid of all that trouble, I have renamed '/sbin/plymouthd' and all is fine here as well. No more hangs with black screen. To see the boot-messages I already reverted to good old grub-legacy.

Unfortunately there is no easy/convenient way to un-install plymouth - so this is considered a dirty hack, but it solves all my problems!
