Comment 19 for bug 473615

I appear to have the same problem yens is having, except I'm not prompted for the passphrase at all. Trying to mount the root device times out and I'm dropped into a busybox shell, where I can manually run cryptsetup luksOpen /dev/sda1 crypt1, but it won't continue booting. This problem appeared randomly, starting with a shared library error with libgpg-error0 not being in the initramfs image. Spent forever fixing that, but I still don't get prompted to enter my passphrase.
