This most likely means that the required crypto kernel modules were not
loaded by the initramfs.

For aes-cbc-essiv:sha256, you need the kernel modules dm-mod, dm-crypt,
aes, cbc, sha256 and blkcipher.

If you use initramfs-tools, add all these to /etc/initramfs-tools/modules
and regenerate the initramfs afterwards.

Maybe some of these modules where compiled into the 2.6.18 kernel while
the 2.6.21 kernel has compiled them as modules.
