Removing linux-azure as this appears to be unrelated. ** No longer affects: linux-azure (Ubuntu)

The issue is: when I use the "resume=UUID=533b2cd9-31ac-449b-82ff- 014f09ab0a9c" kernel parameter for hibernation, due to the missing lines, the variable 'resume' in a later place in "/usr/share /initramfs-tools/init" is set to "UUID=533b2cd9-31ac-449b-82ff- 014f09ab0a9c" rather than "/dev/disk/by-uuid/533b2cd9-31ac-449b-82ff- 014f09ab0a9c". Next, in /usr/share/initramfs-tools/scripts/local- premount/resume: DEV=$(readlink "$resume") DEV=/sys/class/block/${DEV##*/}/dev if [ -r "$DEV" ]; then read -r MAJMIN < "$DEV" fi if [ -z "$MAJMIN" ]; then exit 1 fi Here the 'readlink' will fail, so $DEV is not pointing to a valid device, and then $MAJMIN is empty and we "exit 1", so no resume can happen! Not sure why the 4 lines are removed in Ubuntu 20.04...

The initramfs should be loaded along with the kernel and is then responsible for mounting the root filesystem and starting the main init system.
