After hibernating with systemctl hibernate, the system boots normally as if it had been shutdown. I have the resume parameter in the kernel line and the resume hook in mkinitcpio.conf

These are the relevant kernel messages:

$ dmesg | grep -i swap
[    0.000000] Command line: initrd=\initramfs-linux.img root=/dev/sda2 rw resume=/dev/sda4
[    0.000000] Kernel command line: initrd=\initramfs-linux.img root=/dev/sda2 rw resume=/dev/sda4
[    0.350295] PM: Checking hibernation image partition /dev/sda4
[    8.776686] Adding 8191996k swap on /dev/sda4.  Priority:-1 extents:1 across:8191996k FS
$ dmesg | grep -i hibern
[    0.350295] PM: Checking hibernation image partition /dev/sda4
[    0.350301] PM: Hibernation image not present or could not be loaded.

So the only remaining possibility is that systemctl didn't write to disk. In fact, when I run the command, the screen first goes blank for a couple of seconds, then I can see my terminal again, and finally it shutdowns itself.

I read that pm-utils do not work very well with systemd, so I wouldn't want to switch to those. Any suggestions?

    I had a similar problem. I fixed it by tweaking the resume= kernel option. Find out the UUID of your swap partition and then try to resume=UUID=....... – Adrian Ratnapala Mar 17 '15 at 4:41
  • @AdrianRatnapala: Thanks for the help! I'll try your solution. – rubik Mar 18 '15 at 1:27
  • I have the same problem. Could you please share your solution here? – Hi I'm Frogatto May 28 '15 at 16:01
  • @abforce Following Adrian's solution worked for me. Replace normal paths with UUIDs in the kernel options. – rubik May 28 '15 at 19:12

To elaborate @AdrianRatnapala's comment, you have to:

  1. Find uuid of your swap partition. Suppose the partition is sdb3, then

    $ ls -l /dev/disk/by-uuid/ | grep sdb3
    lrwxrwxrwx 1 root root 10 окт.   9 08:59 1dd7e123-1f82-45f0-a202-0ff3ea6f081a -> ../../sdb3
  2. Open /etc/default/grub, and find the line starting with GRUB_CMDLINE_LINUX_DEFAULT=". Add there between the quotes resume=/dev/disk/by-uuid/your-swap-uuid. As an example:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=/dev/disk/by-uuid/1dd7e123-1f82-45f0-a202-0ff3ea6f081a"
  3. Run as a root update-grub

  • UUID of my swap changes every reboot so this doesn't work :( – Petr Jan 19 '16 at 16:30
  • @Petr this is weird… UUID should only change upon reformatting. I found alike bug-report though, but this is dated by 2008 year. Okay, just for the safe case try sudo mkswap </dev/partition-name>, then check its UUID with sudo blkid </dev/partition-name>. If it still would change upon reboot, I'd suggest you to ask a question at – Hi-Angel Jan 19 '16 at 17:55
  • @Petr ah, another thing to try before asking — you could manually set UUID of swap with sudo swaplabel -U <NEW-UUID> </dev/partition-name>. You could generate new UUID with uuidgen utility. – Hi-Angel Jan 19 '16 at 18:05

    grub-mkconfig -o /boot/grub/grub.cfg in Arch Linux. :) – vmassuchetto Jun 23 '17 at 19:01
