Hi,
ea2062dd1f03 ("drm/amd/display: fix the system hang while disable PSR") was tagged for stable, but failed to apply to 6.3.y, 6.1.y and 5.15.y.
I've looked into the missing dependencies, and here are the dependencies needed for the stable backport:
5.15.y:
97ca308925a5 ("drm/amd/display: Add minimal pipe split transition state") f7511289821f ("drm/amd/display: Use dc_update_planes_and_stream") 81f743a08f3b ("drm/amd/display: Add wrapper to call planes and stream update") ea2062dd1f03 ("drm/amd/display: fix the system hang while disable PSR")
6.1.y / 6.3.y
ea2062dd1f03 ("drm/amd/display: fix the system hang while disable PSR") f7511289821f ("drm/amd/display: Use dc_update_planes_and_stream") 81f743a08f3b ("drm/amd/display: Add wrapper to call planes and stream update") ea2062dd1f03 ("drm/amd/display: fix the system hang while disable PSR")
Is there something missing in that series ?

reverting them from the 6.3.9 build is confirmed to fix the issue.
Is it just the warning, or is there also a functional issue?
here is full boot journals with working 6.3.8 and failing 6.3.9 with those patches applied: https://bugs.mageia.org/attachment.cgi?id=13888
-- Thomas
Interesting; the patches are mostly for fixing PSR which is only enabled on Rembrandt and later.
If possible can you confirm which patch caused it for a better hint of which other dependencies are missing for this APU?
I'm guessing it's specifically " drm/amd/display: Use dc_update_planes_and_stream".
Also; does 6.4-rc7 work properly?
Thanks!
