Can you attach your VBIOS image?  It'll be available under /sys/kernel/debug/dri/0/vbios.rom while nouveau is loaded.
Comment 3 Ilia Mirkin 2017-12-07 19:30:26 UTC
IIRC I had the same issue with my G96. Should be in the vbios repo.

File has been attached. (twice by mistake)

Yeah, as far as I can tell from that, we're not doing anything wrong here.  Your VBIOS' connector table points to a GPIO table entry that doesn't exist.

Ok good. At least we know what the issue is.

I am not familiar with the Video Bios (VBIOS). Does this suggest that there is something wrong with the firmware on the video card? It would be good to get the version of my vbios so that I can find vbios updates. 

Did you see a version? What are you using to access the vbios rom?
