since you somehow changed the UUID of your swap partition, please make sure, that
/etc/initramfs-tools/config.d/resume
contains the correct UUID of your swap partition.
I had a very similar problem here, where GParted (for some reason) changed the UUID of my swap partition during repartitioning. From that time on hibernate stopped working as you described: Ubuntu booted normally instead of resuming from hibernate.
Hmhef,
