It might be just another IOMMU related bug like this older report of mine: #446 (older hardware).

drm/i915: Fix assert_plane() warning on bootup with external display
```
Following the above commit, boot results in a black screen (backlight on) ~13% of the time.
This appears to be timing related. Following hang, machine appears unresponsive (no response to alt-sysrq).
Bisect was carried out with 50 boots per test kernel.
Possibly related to #208 (kernel version match, the first release tag containing commit 516a49 is v4.20).https://gitlab.freedesktop.org/drm/intel/-/issues/9406DRM error - flickering screen with mouse cursor movement - with IOMMU2023-09-26T07:37:24ZJBDRM error - flickering screen with mouse cursor movement - with IOMMU<!--
