Hi *,

yesterday I installed a new XPS13 9310 2-in-1 by preparing the necessary partitions and reovering a backup from an XPS 13 9370. Everything works ok besides resuming from hibernate. For the original XPS13 9370 this still works without any problems.

When running "systemctl hibernate" on the 9310 I get

systemd-sleep[5537]: INFO: running /usr/lib/systemd/system-sleep/grub2.sleep for hibernate systemd-sleep[5537]: INFO: Running prepare-grub .. systemd-sleep[5537]: Skipping openSUSE Tumbleweed, with Linux 5.16.1-1- default (recovery mode), because it has the noresume option systemd-sleep[5537]: Skipping openSUSE Tumbleweed, with Linux 5.16.0-1- default (recovery mode), because it has the noresume option systemd-sleep[5537]: Skipping openSUSE Tumbleweed, with Linux 5.15.12-1- default (recovery mode), because it has the noresume option systemd-sleep[5537]: Skipping openSUSE Tumbleweed, with Linux 5.15.8-1- default (recovery mode), because it has the noresume option systemd-sleep[5537]: Skipping openSUSE Tumbleweed, with Linux 5.15.7-1- default (recovery mode), because it has the noresume option systemd-sleep[5537]: running kernel is grub menu entry openSUSE Tumbleweed (vmlinuz-5.16.1-1-default) systemd-sleep[5537]: preparing boot-loader: selecting entry openSUSE Tumbleweed, kernel /boot/5.16.1-1-default systemd-sleep[5537]: running /usr/sbin/grub2-once "openSUSE Tumbleweed" systemd-sleep[5537]: time needed for sync: 0.0 seconds, time needed for grub: 0.1 seconds. systemd-sleep[5537]: INFO: Done. systemd-sleep[5534]: Entering sleep state 'hibernate'...

I get the same output from "systemctl hibernate" on the 9370. Both have a swap partition with 32 GB in size and 16 GB of RAM. Kernel command line contains resume=UUID=<uuid_of_swap_partition> in both cases.

The only difference I saw is this message, that shows up on the 9310 before systemd-sleep is running:

kernel: PM: Image not found (code -16)

Any idea what might be wrong here?
