System Fails to Resume from Hibernation

This document (000020287) is provided subject to the disclaimer at the end of this document.


SUSE Linux Enterprise Desktop 15 SP3
SUSE Linux Enterprise Server 15 SP3


Putting a system in Hibernation mode, does not execute the resume function, but performs a standard reboot, losing any grey data expected to be saved.


Install a YaST2 patch or enable the resume functionality manually.

a) Install the YaST2 Patch:

For systems where Hibernate / S4 capabilities are required, any system running SUSE Linux Enterprise 15 SP3 GM must be updated with the yast2-4.3.62-3.5.1.x86_64.rpm patch, which can be downloaded from the SUSE Customer Center.

1.       To install the patch, copy the RPM to the Desktop of the system being patched.
2.       Open a Terminal and type zypper in yast2-4.3.62-3.5.1.x86_64.rpm
3.       Reboot the system.

b) Manually Enabling Resume Functionality

Add "resume" to the initrd with the following commands:

# echo 'add_dracutmodules+=" resume"' > /etc/dracut.conf.d/resume.conf
# chmod a-x /usr/lib/systemd/systemd-hibernate-resume
# mkinitrd
# reboot

The first line makes the resume functionality a permanent part of the initrd.


The second line deactivates systemd-hibernate-resume so that Dracut includes /usr/lib/dracut/modules.d/95resume/ in the initrd. does use the resume=... parameter from /etc/cmdline.d/95resume.conf and triggers the resume from userspace as desired.


A regression, due to the missing resume boot parameter

Additional Information

Alternatively disable hibernation:
# systemctl mask
and reboot.

To verify if it's been masked run:
# systemctl status

To re-enable suspend and hibernation:
# systemctl unmask
