Sorry, had to take cover for a Tornado Warning. I had to add agdpmod=pikera in order to boot with that EFI but here is the ioreg. Not much of my system worked with that one though, I guess that is expected.

Disable IGPU from bios!

Try again with that EFI, block WEG from loading, space at the clover boot menu and block.

Same behavior. Drives spin down, USB devices turn off, Fans continue running and all lights on mobo and GPU stay on.
