            Bug ID: 216516
           Summary: s2ram freezes screen (Ryzen-5650U incl. Radeon GPU)
           Product: Drivers
           Version: 2.5
    Kernel Version: 6.0-rc6
          Hardware: AMD
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri at kernel-bugs.osdl.org
          Reporter: kolAflash at kolahilft.de
        Regression: No

Beginning with this commit (regression) s2ram freezes the screen and I have to
restart the XServer.
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=7123d39dc24dcd21ff23d75f46f926b15269b9da
git describe: 5.18-rc7-1-g7123d39dc24d
s2ram => systemctl start suspend.target

Before v5.18-rc7 the system sometimes stays awake instead of entering S3 sleep.
But in that case the system keeps running stable and the screen doesn't freeze.
And on the second try the system then successfully enters S3. You can see this
behaviour in the attached linux-v5.18-rc7.txt for 5.18.0-rc7-v5.18-rc7.
This "stays awake" behaviour is probably a bug on it's own.
(I may may open another bug report when this one is solved)

Later on in the attached linux-v5.18-rc7.txt you'll see how
5.18.0-rc7-v5.18-rc7-1-g7123d39dc24d behaves when the screen is getting frozen.


Reverting commit 7123d39dc on v5.19.10 or v6.0-rc7 makes the problem disappear.


= System =
Model: HP EliteBook 845 G8 (notebook)
CPU+GPU: Ryzen 5650U incl. Radeon GPU
OS: openSUSE-15.4

The HP EliteBook 845 G8 uses s0ix/s2idle by default. But I changed the ACPI
BIOS settings to enable classic S3 s2ram.
