Hi there,
I've a few Laptop and PCs with Fedora 21 and CentOS 7. On all system
resume from hibernate is still working, only on on Laptop (HP Revolve
810). Here are some interesting lines from "journalctl -b":
Jul 27 08:23:43 destnadml00 kernel: Kernel command line:

Jul 27 08:24:08 destnadml00 systemd-hibernate-resume[751]: Could not
resume from '/dev/destnadml00_vg/swap_lv' (253:2).
Why is there a "kernel: PM: Image not found (code -22)"
What I've done:
[root@destnadml00 ~]# cat /etc/default/grub
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.lvm.lv=destnadml00_vg/root_lv
rd.luks.uuid=luks-9927c3a0-13dd-4a34-ac0f-984d37cd7803
rd.lvm.lv=destnadml00_vg/swap_lv rd.luks.options=discard root_trim=yes
resume=/dev/destnadml00_vg/swap_lv rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
[root@destnadml00 ~]#grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
Thanks
Andreas
