Lenovo z50-70 igpu timeout

[DawidCylke]

Hey guys. I successfully installed Sierra on my SSD but have problems booting it with clover installed on SSD. I can boot from install USB stick but when I'm trying to do it from SSD I get timeout igpu like in the attached image.

I tried different config files without any luck. I think it might be something with kexts. What do you think?

Your ACPI is missing PNLF device, you probably forgot to apply "Brightness Fix" patch.
