You have been subscribed to a public bug: When booting with an encrypted root partition, I'm unable to enter the password when prompted during boot. Rebooting by hitting Ctrl+Alt+Del twice, displays grub menu and then puts me in a degraded mode of some sort where I can enter the password and boot successfully. Disabling splash in grub options works too by using a text mode password input.
This seems to have been introduced in some of the recent updates. It used to work fine after my initial installation of 15.04.
