# Смещение поделил на размер блока 4096
# For some reason the output of the script is misaligned, but it's not that difficult to find the proper value: it's the first number in the rightmost column shifted slightly to the left. For me it's 44418101248. Divide this value by 4096 and that's your resume_offset. Mine is 44418101248 / 4096 = 10844263
$ echo $((`sudo btrfs_map_physical /swap/swapfile | head -n 2 | tail -n 1 | cut -f9` / 4096))
22224
В /etc/default/grub прописал:
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet resume=UUID=06572f2c-bd18-494f-a2b6-904704d5222e resume_offset=22224"
В хуки /etc/mkinitcpio.conf добавил resume после filesystems.
Выполнил:
sudo mkinitcpio -p linux
sudo grub-mkconfig -o /boot/grub/grub.cfg
$ systemctl hibernate
Failed to hibernate system via logind: Not enough swap space for hibernation

У кого-нибудь есть решение?
