Hibernation

Hi trying to get hibernation to work.

This is my system before I started:

1 SSD
4 OS's on that SSD (ElementaryOS, Windows, CentOS and Arch Linux) on different partitions
My home folders for the linux OS's are stored on a seperate partition.
Using Gnome Cinnamon Hibernate has no effect seemingly
fstab:

# /dev/sda4
UUID=614c6989-66cb-4173-8384-7bd86fefcb39	/         	ext4      	rw,relatime,data=ordered	0 1

# /dev/sda6
UUID=a018da02-9ee8-449f-9a18-634f247d9ed2	none      	swap      	defaults,pri=-2	0 0

#dev/sda5
UUID=f9c42c03-c2bc-4d5d-ba27-baeb5aa80659   /media/DATA ext4        defaults,rw,errors=remount-ro    0   0
/media/DATA/arch    /home   bind    defaults,rw,errors=remount-ro,bind   0   0

Default OS is ElementaryOS, which has a grub2 bootloader I will later edit with Grub customizer

The swap partition is shared so first thing I did was create a swap file
I created the file, and added the entry to fstab '/swapfile swap swap defaults, pri=-3 0 0'
This is what swap -s looks like now

Filename				Type		Size	Used	Priority
/swapfile                              	file    	6291452	0	-2
/dev/sda6                              	partition	12582908	0	-3

Btw, why are the priorities the wrong order? the priority of swapfile is lower than that of dev/sda6 in my fstab? (I get the same result setting pri=-100 for /swapfile) Should this be set somewhere else?

Then I entered the variables (resume, resume_offset) via grub customizer

grub.cfg (This is in the /boot/grub of ElementaryOS partition)

### BEGIN /etc/grub.d/40_custom_proxy ###
menuentry "Arch (on /dev/sda4)" --class gnu-linux --class gnu --class os $menuentry_id_option 'osprober-gnulinux-simple-614c6989-66cb-4173-8384-7bd86fefcb39' {
	insmod part_gpt
	insmod ext2
	set root='hd0,gpt4'
	if [ x$feature_platform_search_hint = xy ]; then
	  search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt4 --hint-efi=hd0,gpt4 --hint-baremetal=ahci0,gpt4  614c6989-66cb-4173-8384-7bd86fefcb39
	else
	  search --no-floppy --fs-uuid --set=root 614c6989-66cb-4173-8384-7bd86fefcb39
	fi
	linux /boot/vmlinuz-linux root=/dev/sda4
	initrd /boot/initramfs-linux.img
	resume=UUID=614c6989-66cb-4173-8384-7bd86fefcb39
	resume_offset=7208960
}

The UUID is pointed at / and not at /home partition as swap path is /swapfile correctly I think and the the resume_offset is filefrag

Filesystem type is: ef53
File size of /swapfile is 6442450944 (1572864 blocks of 4096 bytes)
 ext:     logical_offset:        physical_offset: length:   expected: flags:
   0:        0..       0:    7208960..   7208960:      1:

Finally, I added the hook resume with sudo nano /etc/mkinitcpio.conf as recommended and ran sudo mkinitcpio -p linux

Basically exactly as the wiki says I think.
However, Hibernating has the same behavior as before, that is the screen shows the lock screen, goes black a couple times and lights back up before shutting down.
Booting it back up, its just as if I started it up normally.

My journalctl shows this:

when hibernating at the end

when shutting down:

regardless of which way I shut down, when starting up, these appear:

I think I should provide more dmesg/journalctl logs but I don't know what's useful and they seem kind of long. If requested Ill put them up.

May 30 21:47:59 archlinux kernel: PM: Image not found (code -22)

Seems like a problem but I don't know what it means/ Its weird because again I get the PM hibernation nosave memory starting up whether I hibernate or not and I think my grub config is correct as well. I don't know where I could have made a mistake
