   I've installed

     mobo:   ASRockRack X470D4U
     bios:   vP4.20, 04/14/2021
     cpu:    Ryzen 5 5600G
     OS/kernel: Fedora34/Linux, kernel v5.14.13-200

I have 2 GPUs installed,

(1)     an NVidia PCIe card

     NVIDIA GK208B [GeForce GT 710]
     driver: 'nvidia'

and

(2)     the Ryzen CPU-integrated

     Advanced Micro Devices [AMD/ATI] Cezanne driver: N/A
     driver: 'gpu'

On boot, NVidia has no issues.
But, amd-gpu reports a 'fatal error' and 'failed' probe,

     dmesg | grep -i amdgpu

          ...

I've posted full details in a thread on "amd-gfx" ML,

     amdgpu "Fatal error during GPU init"; Ryzen 5600G integrated GPU + kernel 5.14.13
      https://lists.freedesktop.org/archives/amd-gfx/2021-October/070709.html

In that thread, upstream suggests it's a BIOS issue:

     "The driver is not able to find the vbios image which is required for
     the driver to properly enumerate the hardware.  I would guess it's a
     platform issue.  Is there a newer sbios image available for your
     platform?  You might try that or check if there are any options in the
     sbios regarding the behavior of the integrated graphics when an
     external GPU is present.  I suspect the one of the following is the
     problem:
     1. The sbios should disable the integrated graphics when a dGPU is
     present, but due to a bug in the sbios or a particular sbios settings
     it has failed to.
     2. The sbios should be providing a vbios image for the integrated
     graphics, but due to a bug in the sbios or a particular sbios settings
     it has failed to.
     3. The platform uses some alternative method to provide access to the
     vbios image for the integrated graphics that Linux does not yet
     handle."

Beyond the trace , and comments, above it's not clear how to confirm/exclude the BIOS as problem.

Screenshots of current BIOS settings are:

Are there different/additional settings @ BIOS &/or kernel config options req'd to get amdgpu to boot without error?

Or is this a BIOS bug?

I've posted full details in a thread on "amd-gfx" ML, amdgpu "Fatal error during GPU init"; Ryzen 5600G integrated GPU + kernel 5.14.13 https://lists.freedesktop.org/archives/amd-gfx/2021-October/070709.html In that thread, upstream suggests it's a BIOS issue: "The driver is not able to find the vbios image which is required for the driver to properly enumerate the hardware. I would guess it's a platform issue. Is there a newer sbios image available for your platform? You might try that or check if there are any options in the sbios regarding the behavior of the integrated graphics when an external GPU is present. I suspect the one of the following is the problem: 1. The sbios should disable the integrated graphics when a dGPU is present, but due to a bug in the sbios or a particular sbios settings it has failed to. 2. The sbios should be providing a vbios image for the integrated graphics, but due to a bug in the sbios or a particular sbios settings it has failed to. 3. The platform uses some alternative method to provide access to the vbios image for the integrated graphics that Linux does not yet handle." Beyond the trace , and comments, above it's not clear how to confirm/exclude the BIOS as problem. Screenshots of current BIOS settings are: Are there different/additional settings @ BIOS &/or kernel config options req'd to get amdgpu to boot without error? Or is this a BIOS bug?

	Hi, I have the same problem with this board and the Ryzen 7 5700G CPU. On Linux installs (Ubuntu as well as Proxmox) I get amdgpu 0000:30:00.0: amdgpu: Unable to locate a BIOS ROM I also tried a Windows install and get an error 43 for the APU. Is there a Bios Update I'm currently running P4.20 or a Setting I need? Thanks for any help :)

	Same problem Here. Ryzen 5650G and 5750G. BIOSes for X470D4U are very buggy.

	The driver tries multiple methods to fetch the vbios depending on the platform. One of the methods fails and this message is the result. anyway, your linux needs updates i believe kernel 5.11 and mesa 21.3 are minimum for 5600G with command inxi -Fxrz you can check your kernel and mesa versions Edited by kerberos_20 - 10 Feb 2022 at 9:37am

	Tried kernels 5.15, 5.16, 5.17 RC and the latest firmware for Cezanne APUs (codename Green Sardine) of course, no change. ASrock sent me unofficial BIOS L4.23 for x470d4u motherboard, it didn't work. I am waiting for their next message.

	tbh linux is quite user friendly... you could load gpu firmware (bios image) manually https://wiki.gentoo.org/wiki/AMDGPU cezanne has mentioned this path for firmware blob amdgpu/green_sardine_{asd,ce,dmcub,me,mec2,mec,pfp,rlc,sdma,ta,vcn}.bin load it up with https://wiki.gentoo.org/wiki/Genkernel#Firmware_loading

	Using Gentoo many years and exactly this firmware was used. No luck. When I swap motherboard to Asus B450, kernel module loads without error.

	So what IS actually buggy, the Motherboard or the BIOS?

	I have the same problem and was about to get crazy as I wanted to use the iGPU to fasten ffmpeg processes on the server. ASRockRack X570D4U / Ryzen 7 PRO 5750G Any hints for solutions?
