the issue reported below is unrelated, see my comment there, could you re-report this result?

There is no HPD IRQ raised or handled on the above host, so the changes are not related to it.

The issue is:
<3> [158.833677] i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun

It seems to happen frequently, on the same host, leading to incorrect BAT failures.

There is
https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/12935

but on a different host (MTL).
