Public bug reported: Roughly every other time, hibernating (via systemctl hibernate) fails : it begins then I get back to lightdm prompt.
journalctl shows the lines systemd[1]: Starting Hibernate... systemd-sleep[22333]: Spawned /lib/systemd/system-sleep/10_unattended-upgrades-hibernate as 22334. systemd-sleep[22333]: Spawned /lib/systemd/system-sleep/hdparm as 22335. systemd-sleep[22333]: Spawned /lib/systemd/system-sleep/10_grub-common as 22336. systemd-sleep[22333]: Spawned /lib/systemd/system-sleep/wpasupplicant as 22337. systemd-sleep[22333]: Spawned /lib/systemd/system-sleep/tuxonice as 22338. systemd-sleep[22333]: Spawned /lib/systemd/system-sleep/back_to_ram as 22339. systemd-sleep[22333]: /lib/systemd/system-sleep/10_unattended-upgrades-hibernate succeeded. systemd-sleep[22333]: /lib/systemd/system-sleep/back_to_ram succeeded. systemd-sleep[22333]: /lib/systemd/system-sleep/hdparm succeeded. systemd-sleep[22333]: /lib/systemd/system-sleep/tuxonice succeeded. systemd-sleep[22333]: /lib/systemd/system-sleep/10_grub-common succeeded. systemd-sleep[22333]: /lib/systemd/system-sleep/wpasupplicant succeeded. systemd-sleep[22332]: system-sleep succeeded. systemd-sleep[22332]: Suspending system... kernel: PM: hibernation entry kernel: PM: Syncing filesystems ... kernel: PM: done. kernel: Freezing user space processes ...
