I had a RESUME=/dev/... in /etc/initramfs-tools/conf.d/resume
Changing it to RESUME=UUID=.... and running 'update-initramfs -u' fixed it.
It would help if, both during boot and update-initramfs rungs, a message was printed when theRESUME= line seems to be incorrect (wrong UUID or device name instead of UUID).
