Hi, I had the exact same problem (J5005 NUC) and I _think_ I fixed it by
accident just the other day by swapping HDMI cables. It has not happened for
two days so far, so fingers crossed. It it happens again, I will try to
recreate the issue with drm-tip.

Otherwise the procedure to get it up and running was the same as you describe,  
- shutdown xorg
- unload module
- load module
- restart xorg

No idea on why the HDMI cable would be an issue though. 

My setup is kinda similar to yours:

NUC --> HDMI splitter (4 inputs, 1 output) -+---> HDMI Projector
                                            |
                                            +---> S/PDIF Speakers
