[HELP] Early EFI boot failure when iGPU is enabled (SMBIOS: MacPro7,1)

[HELP] Early EFI boot failure when iGPU is enabled (SMBIOS: MacPro7,1)

Hi all,

My hack has been running stable (kinda) for a while and now I would like to enable the integrated GPU for HEVC decoding and stuff. But it doesn't work, if I have it then Recovery and installer won't boot at all (see photo attached). Sometimes the actual macOS will boot, but then my thunderbolt card stops working. I have a AKiTiO HDD box attached, the system can sometimes see the disks but it won't mount and after a while it disappears. And after a reboot it also fails to boot. I'm using the latest Clover release and MacPro7,1 SMBOIS, if needed I'll attach my EFI folder.

Thanks for any help.
