I remember that it worked before, it definitely worked on my previous laptop. Because of this problem, I temporarily had to abandon encrypted swap since I need hibernation. and this is unsafe. -- You are receiving this mail because: You are on the CC list for the bug.

Could you please `zypper dup` and check if this is still reproducible with the latest systemd version. If that's the case, please set `systemctl log-level debug`, issue `systemctl hibernate` and attach the output of `journalctl -b -o short-monotonic`. Thanks!
So. I again created luks encrypted swap, added a key file to it, registered it in fstab, crypttab and kernel cmdline as indicated in the manual, but I never got around to testing hibernation. Now the system simply does not boot with this resume in cmdline (to boot I manually erase this parameter by editing the menu item in grub), the system simply cannot start using swap with this uuid.

in my opinion it can be called “it has become worse”. or I forgot to do something, but I don’t understand what.
The UUID in fstab and the resume kernel command line option (/etc/default/grub) is wrong, it should be `855f2aa2-2f74-4f5f-9197-825c406b84ab`.
ok, I checked when changing the resume parameter in cmdline from uuid swap partition to uuid luks partition with swap partition, the system boots correctly but if the same change is made in fstab, then after booting the system swap will be unused. which in my opinion is logical, because this uuid does not point to swap but to luks encrypted partition. I returned the uuid swap partition to swap, and left uuid luks with swap in cmdline, so the system booted correctly and swap worked. however, this did not lead to hibernation working:

Sorry, I should've asked to add `systemd.log_level=debug` in the kernel command line to be able to see what's happening. But, I was able to reproduce your issue locally, and the logs match what you wrote in comment #1:

With the following actions I managed to make it work: - Set `resume=/dev/mapper/cr_swap` on the kernel command line. - Remove `add_device+=" UUID=... "` from /etc/dracut.conf.d/99-resume.conf - In /etc/crypttab, append the following two options to the cr_swap entry (4th column): x-initrd.attach,force - Run `dracut -f` - Reboot and try again `systemctl hibernate`.
If it does not work in your system, add `systemd.log_level=debug` and attach the output of `journalctl -b -o short-monotonic`. Thanks.
I'm back with good news As I understand it, adding `x-initrd.attach` to crypttab helped. Now hibernation works as it should. it might make sense to note this in the documentation from the first comment. wi-fi does not work when waking up, but this is not the topic of this bugreport. thanks for help! -- You are receiving this mail because: You are on the CC list for the bug.
