Hi,

this is related to:
https://gitlab.freedesktop.org/drm/amd/-/issues/4009

As per Mario's recommendation, I'm also opening a report here, although my
layman instincts suggest that something's wrong on the AMD side of things.

My framework laptop 13 with an AMD 7840U chip behaves unpredictably after
waking up from sleep. At times everything works fine, other times it spirals
down into freezes that force me to power off and start from scratch. Those
freezes are usually preceded by blocky artifacts or kwin animations repeating
in loop, like minimizing a window.

System info:

Operating System: openSUSE Tumbleweed 20250304

If you don't mind I would keep attachments in the aforementioned ticket on the
freedesktop drm/amd project, to avoid duplicates. If you do mind, please let me
know and I'll make sure to upload my attachments/logs in both tickets.

Thanks
