[KSB] I don't know any way to suspend to disk with an encrypted swap
partition, because suspend to disk (Hibernate)recognizes that the swap
space has a memory image in it and loads that memory image (simplified
explanation). If the swap space must have an encryption key entered
before it can be booted, then you can no longer restore from swap. So
I only use suspend to RAM (Suspend).
