The above host doesn't have any MST output connected to it, so none of
the changes in the patchset should have an effect on it.

The failure is

<3> [163.445434] i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun

and looks to be the same issue as the one reported in
https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/12914
