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.
