            Bug ID: 216917
           Summary: hibernation regression since 6.0.18 (Ryzen-5650U incl.
                    Radeon GPU)
           Product: Drivers
           Version: 2.5
    Kernel Version: 6.0.18
          Hardware: AMD
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Platform_x86
          Assignee: drivers_platform_x86@xxxxxxxxxxxxxxxxxxxx
          Reporter: kolAflash@xxxxxxxxxxxx
        Regression: No

Since Linux-6.0.18 hibernation isn't working anymore. 6.0.17 was working fine.

When doing
  systemctl start hibernate.target
the screen turns black, but the system doesn't power down.
Same problem for "platform" and "shutdown" in /etc/systemd/sleep.conf =>
HibernateMode.

Force rebooting the system makes GRUB skip the boot menu (like normal when
waking from hibernation), but the system just boots up freshly, not restoring
the old state.


= System =
Model: HP EliteBook 845 G8 (notebook)
CPU+GPU: Ryzen 5650U incl. Radeon GPU
OS: openSUSE-15.4
Kernel: compiled from kernel.org
The HP EliteBook 845 G8 uses s0ix/s2idle.


Sadly I don't know how to provide helpful logs. After reboot there's nothing
helpful in /var/log/messages
Just this:
