When I use systemd.log_level=debug systemd.log_target=console in the kernel parameters, and then do systemctl hibernate during the system I get: Mar 29 12:04:48 hbt systemd-logind[780]: Got message type=method_call sender=:1.9 destination=org.freedesktop.login1 path=/org/freedesktop/login1 interface=org.freedesktop.login1.Manager member=SetWallMessage cookie=2 reply_cookie=0 signature=sb error-name=n/a error-message=n/a Mar 29 12:04:48 hbt systemd-logind[780]: Sent message type=method_return sender=n/a destination=:1.9 path=n/a interface=n/a member=n/a cookie=61 reply_cookie=2 signature=n/a error-name=n/a error-message=n/a Mar 29 12:04:48 hbt systemd-logind[780]: Got message type=method_call sender=:1.9 destination=org.freedesktop.login1 path=/org/freedesktop/login1 interface=org.freedesktop.login1.Manager member=HibernateWithFlags cookie=3 reply_cookie=0 signature=t error-name=n/a error-message=n/a Mar 29 12:04:48 hbt systemd-logind[780]: Sleep mode "disk" is supported by the kernel.

Does that mean it's the same problem as with the desktop environment? I.e. systemdctl first asking logind whether hibernate was available, before even starting hibernate.target? Thanks, Chris.
