Bug#514404: also for lvm2 devices

Wed May 6 11:01:55 UTC 2009

The same is true if your encrypted root partition is on a LVM2 volume group.
Then one also has to add "lvm2" by hand 
to /usr/share/initramfs-tools/scripts/local-top/loopaes and regenerate the 
initramfs.

This bug is escpecially on new installs where you can in this way happily 
create unbootable systems.

In my case it was the combination of loop-aes/LVM2/RAID which created an 
unbootable system.
