When your hibernated session fails to resume, most of the time your resume partition is wrongly configured in initramfs.

cat /etc/fstab and look for a line like:
# /dev/sda7
UUID=3a3ee660-d330-4c36-847e-54fe39f1d45c swap swap sw 0 0

edit /etc/iniramfs-tools/conf.d/resume
Make sure you have the correct uid;
RESUME=UUID=3a3ee660-d330-4c36-847e-54fe39f1d45c

And update your initramfs;
sudo update-initramfs -u

Done.
