When trying to configure hibernation on Noble Numbat, systemd-sleep hibernate complains about
"Failed to find location to hibernate to: Invalid argument" caused by a "0:0" entry in /sys/power/resume
Current configuration:
1) Legacy boot configuration (non-UEFI!)
2) Dual swap space configuration (/etc/fstab excerpt for swap partition and file):
UUID=c323a060-1b69-48af-a5bb-395f5d05fb60 none swap sw 0 0
/swap none swap sw,pri=2 0 0
2) resume config in /etc/initramfs-tools/conf.d/resume with the correct UUID and offset:
RESUME=UUID=7799882e-189c-484b-b9d4-f9e302859b0b resume_offset=39608320
(blkid: /dev/sda1: UUID="7799882e-189c-484b-b9d4-f9e302859b0b" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="4f6b947f-01")
3) Correct grub config:
GRUB_CMDLINE_LINUX="resume=UUID=7799882e-189c-484b-b9d4-f9e302859b0b resume_offset=39608320 acpi_enforce_resources=lax"
Suspect a regression issue with systemd-255 as the issue did *not* appear with Focal Fossal (system-245) and only surfaced after the upgrade to 24.04.
Work-around:
Amend /etc/rc.local (if this is enabled via systemd) with:
"lsblk | fgrep <insert device path holding the swap file> | cut -d' ' -f4 >/sys/power/resume" |

(swap file is the primary and only option for hibernation as partition is too small)
