Ubuntu 20.04 LTS 2. initramfs-tools-core 0.136ubuntu6 3. I expect the system to resume from hibernation when running pm_hibernate 4. The system starts up anew when I try to resume I have setup a swap partition on /dev/vda2 in /etc/fstab. To enable hibernate I added the kernel parameter "resume=/dev/vda2" to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub and run update-grub. From debugging initramfs it tries to follow a symbolic link DEV=$(readlink "$resume") (see /usr/share/initramfs-tools/scripts/local-premount/resume, line 35) which works well when swap is specified with uuid. When swap is specified as a device directly the readlink returns an empty string and the system does not resume from hibernation. To verify this I added the parameter -f to readlink and run "update- initramfs -u". The system now hibernates successfully.
