Hello everyone,
I'm having a persistent issue trying to boot Arch Linux on my system. The boot process freezes shortly after loading the kernel, showing ACPI errors and a GPU initialization failure or just black screen.
Boot logs: https://0x0.st/P_l-.txt
Hardware Specifications:
CPU: AMD Ryzen 5 5500
GPU: AMD Radeon RX 480 (Polaris)
Motherboard: ASUS TUF B450
Monitor Resolution: 1920x1080 75hz
The Problem:
I'm getting the following errors during boot:
ACPI BIOS Error (bug): Failure creating named object... AE_ALREADY_EXISTS
amdgpu: Fatal error during GPU init
amdgpu: probe with driver amdgpu failed with error -110
What I have already tried:
Adding amdgpu to MODULES in mkinitcpio.conf and moving kms hook.
Blacklisting simpledrm and radeon.
Using GRUB parameters: initcall_blacklist=simpledrm_platform_driver_init, amdgpu.dc=0, pci=noacpi, and acpi=off (only acpi=off allows me to reach the login, but with software rendering and high CPU usage).
The system works perfectly on Windows, so it seems to be a Kernel/ACPI conflict with this specific hardware combination.
I can only boot into a functional (but slow) environment using nomodeset or acpi=off. Without them, the driver fails to probe the GPU (Error -110).

Basically, I had to disable IOMMU in the bios; it was causing a conflict with the gpu and the kernel, thanks for nothing guys xd.
