Comment # 8 on bug 860729 from Stanislav Brabec

pm-hibernate itself is a source of many suspend problems (exactly a link
between pm-hibernate and userspace suspend utilities).

As a first step of debugging of all suspend/hibernate problems in Tumbleweed,
it's proposed to:

1. Uninstall package pm-utils.

2. Uninstall package suspend.

3. Try Suspend/Hibernate by calling of "systemctl suspend" or "systemctl
hibernate" (all desktop environments should now support this way to hibernate).

pm-hibernate will not be available any more. There will be a Tumbleweed update
soon that will automatically uninstall both upper mentioned packages.

>From now on, only kernel implementation of hibernation and suspend and only
suspend initiated by systemd are supported.

Userspace suspend that was used by pm-utils calling utilities from suspend
package caused more problems that it solved.
