Bug Description

After the Grub menu, both my screens become black, report no signal, and the boot process seemingly freezes. If I press any button on the keyboard, both screens light up, displaying a password prompt for the disk. If I enter the password, the system continues booting normally, though without any other confirmation that I entered the correct password.

I have a Luks encrypted volume with the following entry in /etc/crypttab, and my graphics card is a RV770-based ATI Radeon HD:
# <target name> <source device> <key file> <options>
storage /dev/disk/by-uuid/9691a45d-e961-4fa3-8d8d-ff24b78e58a0 none luks
