the failure is unrelated, see below, could you please re-report this
result?

There is only an HDMI output on the above machine, so the DP only
changes in this patchset shouldn't have an effect on it.

The failure is:
<3> [200.000799] i915 0000:00:02.0: [drm] *ERROR* CPU pipe B FIFO underrun

and has already an open ticket:
https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/12379

Earlier several CI runs failed on the same RPL_S machine (in different
tests), always on HDMI/pipe B:
