I've tracked this down to 2 patches: 1. 24576d23976746cb52e7700c4cadbf4bc1bc3472 drm/i915: enable VT switchless resume v3 This commit stops the screen from turning back on. Without the patch the screen resumes back to on, however it is filled with random vertical lines. 2. fa55583797d12b10928a1813f3dcf066637caf5e drm/i915: fixup the plane->pipe fixup code I have to manually revert this. If I don't I get the random vertical lines on resume.

If you revert the switchless resume patch, then grab intel_reg_dumper output before and after resume, that will highlight what the bios touched. In fact, if you grab intel_reg_dumper after resume with each patch reverted (none, only switchless patch reverted, both patches reverted) that is likely to have sufficient information to figure out both bugs.
