Kernel logs with amdgpu.dpm=0 (showing the bug)
1. Please describe the problem:
I have a system with a Ryzen 5600G APU and a Vega 64 GPU. When the kernel parameter amdgpu.dpm=0 is used, the APU isn't initialized successfully, with a "smu firmware loading failed" error. The Vega 64 is initialized correctly. See "dmesg-bad.txt".
The same system works fine without "admgpu.dpm=0". I will attempt to add a second attachment after filing with logs on a successful boot (Bugzilla doesn't seem to support more than one attachment at filing time?)
2. What is the Version-Release number of the kernel:
Linux fedora 5.16.12-200.fc35.x86_64
3. Did it work previously in Fedora? If so, what kernel version did the issue
*first* appear? Old kernels are available for download at
Unsure, just bought this APU.
4. Can you reproduce this issue? If so, please provide the steps to reproduce
the issue below:
Yes. I believe having a Ryzen 5600G APU is sufficient, but I haven't been able to test without the Vega 64. But anyway: try to boot with a 5600G + Vega 64, then "lspci -k" notice that the APU device has no "driver in use":
30:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cezanne (rev c9)
Subsystem: Advanced Micro Devices, Inc. [AMD/ATI] Device 1636
Kernel modules: amdgpu
Alternatively, connect a display on the APU and attempt to use it.
5. Does this problem occur with the latest Rawhide kernel? To install the
Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
``sudo dnf update --enablerepo=rawhide kernel``:
I am running Silverblue and I'm not sure how to do this.
6. Are you running any modules that not shipped with directly Fedora's kernel?:
7. Please attach the kernel logs. You can get the complete kernel log
for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
issue occurred on a previous boot, use the journalctl ``-b`` flag.

Kernel logs WITHOUT amdgpu.dpm=0 (everything works fine, for comparison)
Adding logs from a boot without "amdgpu.dpm=0": everything works fine in this case.
(Side note: I am running with amdgpu.dpm=0 because I experience occasional hangs on my Vega 64 in graphically intensive games without it. It is hard to reliably reproduce, but if you want I can try to file that bug too. This thread by me has more details: https://ask.fedoraproject.org/t/gpu-hang-how-could-i-investigate-fix-this/20124/10?u=danutsu)
