--- Comment #20 from Tomeu Vizoso <tomeu at tomeuvizoso.net> ---
Kevin, I think this bug should remain open until the i915 driver becomes able
to get a more accurate clock with 12bpc. This should be possible by using clock
bending to match the desired refresh rate but this is a change that would
considerably complicate clock handling in the code and so far nobody has
started work on this.

That said, I'm reducing the priority to medium because there's a workaround
that restores the previous behavior (replacing the edid with
drm_kms_helper.edid_firmware), and my understanding is that the Highest
priority is reserved for regressions that don't have a known workaround.
