There are a few things that need to be checked, in the initramfs we should have modules for aes cbc and or ecb (I think their built into the kernel so no modules needed) We also need to have encryptfs-utils and cryptsetup stuff in the initramfs. I have only 32 bit architecture available to me, im going to check all this out on my livecd. If someone could do the same for the 64bit livecd and report back I can really use the info.

Can you check if this can be reproduced with raring ?
If not, then it's a regression caused by recent cryptsetup changes, resulting in ecryptfs-utils not added to the initramfs during the cd build.
