This is actually really easy to reproduce. Any N100 or N97 cpu will also
have this bug. I cannot recompile the kernel to test the latest drm-tip
though, but if someone else on this mailing list can, we would appreciate
it if you would post your findings on the gitlab bug
https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/12246

Either that or maybe suggest a PPA Ubuntu kernel repo that has a newer
version of drm-tip that we can test

Cheers
Angelo
