Hi,
the encrypted swap partition is at fault. You see, when the system is
started, that partition is encrypted with a random key; that key is
thrown away when the system powers down (or hibernates). So, when you
suspend to disk, it writes everything into the encrypted swap partition,
but then shuts down and forgets the key. So when you try to resume, it
can't decrypt the image.
So, long short story, setup unencrypted swap or encrypted swap with a
static key.
