I had that problem as well, back then /etc/initramfs-tools/conf.d/resume had a wrong UUID for my swap partition. I guess somewhere in between installing cryptsetup, or ubiquity configuring an encrypted swap partition through ecryptfs-utils (I selected "encrypt my home dir" on install) it either wrote a wrong "resume" file right from the start, or something later on changed it. I didn't really notice before as I never use hibernate.
