As well known the 660 had this bug where after a dozen of minutes the VRAM would fill up and everything on screen would become glitchy. It was still kind of usable and anyway I had my new RX 580 coming soon so couldn't really complain.
Now I have installed the RX 580 and I am not able to boot anymore, neither in the system nor in the installer. I have checked the ID of the card on Windows on GPU-Z and sure enough it's 67DF as it was supposed to be, so it should be supported by just using Lilu and WhateverGreen, but I have both kexts in my efi and I still can't boot.
I get stuck at around "HPET map device registers failed" and whatever line comes after that usually gets truncated as the pc just hangs.
Things i have tried:
Booting with -radvesa, booting with -radoff, booting with DeInit, reinstalling clover on a USB and starting from scratch with the Vanilla AMD Github config.plist + drivers and kexts suggested in the guide, deleting Name-DSDT in the config.plist, using 0x67DF1002 as (non)FakeID, using a different Clover version.
Attaching my EFI partition, any help is appreciated . Thanks in advance!
