I just want to mention that I had the similar problem on a laptop Dell
Lattitude 5590 with "Intel Corporation UHD Graphics 620 (rev 07)".

Luckily I was able to find this bug report and fixed it by applying patch from
https://patchwork.kernel.org/patch/10003565/ "drm/i915: check pin validity of
VBT configurationlogin".

I applied the patch to v4.16 linux kernel tag, so it requires small
modifications. I see that https://patchwork.kernel.org/patch/10180851/
"drm/i915/cnp: Ignore VBT request for know invalid DDC pin." could help, but it
seems more like a quirk.

Could someone promote these solutions into mainline/longterm kernels? Or it is
already in queue and will be included in next releases?
