<pre>Hmm, yes 4.32 is what the BIOS uses, so this might even help:
[ 1.391106] [drm:intel_dump_pipe_config [i915]] port clock: 432000, pipe src
size: 3840x2160, pixel rate 533299
Hmm. That probably means this is a victim of commit f11cb1c19ad0 ("drm/i915/dp:
revert back to max link rate and lane count on eDP"), which I think would have
picked the lower link rate for us.
Yes, eDP revision seems to be 1.4a:
[ 1.385017] [drm:intel_dp_init_connector [i915]] eDP DPCD: 04 92 a5
so I believe that is indeed what would have happened.</pre>
