For some reason when I add SSDT-PNLFCFL.aml to my ACPI patched folder, the black screen issue doesn't occur anymore, but the backlight level isn't maintained when rebooting. Using the SSDT-PNLF.dsl included in WhateverGreen caused my backlight to be really dim, but the black screen didn't occur either.

If your Brightness level isn't maintained after reboot, try adding SSDT-ALS0 : https://github.com/RehabMan/OS-X-Clover-Laptop-Config/blob/master/hotpatch/SSDT-ALS0.dsl into your EFI/Clover/ACPI/Patched "saved as .aml" (while assuming your have working NVRAM).

Reboot, put brightness to a certain level, reboot again and see if it starts saving your last level.

I already have it in my patched folder. For some reason the brightness is retained only on shutdown and not on reboot
