When using dolvm and crypt_root to point to an LVM managed, LUKS-encrypted root ext3 filesystem, the initramfs fails to unlock the encrypted root. The exact same settings work with the scripts provided by 3.4.9, but not 3.4.10. Reproducible: Always Steps to Reproduce: 1. Use genkernel 3.4.10 to create kernel for encrypted LVM2 root filesystem. 2. Setup GRUB to boot the kernel with proper options. 3. LUKS fails to find a key on any partition. 4. Repeat same steps with 3.4.9, and it succeeds. Actual Results: Gentoo/x86 2008.0 profile laptop.

With genkernel 3.4.10, the succeeds at all stages, except the: cryptsetup luksOpen command fails with: No key available with this passphrase. Using the 'shell' option, an lsmod reveals that the output of lsmod are identical with both genkernel 3.4.9 and 3.4.10. Also /proc/crypto are identical with both versions. Also, both properly mount the ext2 root_keydev to /mnt/key. I am able to 'cat' the contents of /mnt/key/root.key with 3.4.9 and 3.4.10. Expected Results: Expected boot-up to be identical with both genkernel versions. Instead, 3.4.10 cannot perform luksOpen.

By "shell" option, I am refering to: The root block device is unspecified or not detected. Please specify a device to boot, or "shell" for a shell..

INVALID and SOLVED. There was a difference between the two genkernel configurations. One was loading module dm-crypt and the other was not. Loading / compiling-in dm-crypt solved the issue.
