I'm guessing this is [1] fixed by commit d3a7051841f0 ("drm/i915/bios: Use hardcoded fp_timing size for generating LFP data pointers") in v6.1-rc1. I don't think this is the root cause for your issues, but I wonder if you could try v6.1-rc1 or drm-tip and see if we've fixed the other stuff already too? BR, Jani.
