Public bug reported:

I've seen the following in syslog during some hibernation failures on
xen systems on both the 4.15 xenial kernel and 5.3 bionic kernel:

anymore. Stopping.

entered failed state.
Aug 26 05:45:17 ip-172-31-2-199 systemd[1]: systemd-hibernate.service: Failed 
with result 'exit-code'.


The end result is hibernation never takes place and the instance is forced to 
reset after 20 minutes.
