have to correct me: 5.12.0 shows this error too, so error not caused by drm-patches, but i guess unrelated to the possible irq issue causing hdmi not working on 5.13 (wait-for-vblank/page_flip tracebacks)

i'm not aware who is also involved in the problem, so i want to avoid send people to the wrong way :)

regards Frank
