            Bug ID: 216840
           Summary: AMDGPU trace message at boot
           Product: Drivers
           Version: 2.5
    Kernel Version: 6.1.0
          Hardware: AMD
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: low
          Priority: P1
         Component: Video(DRI - non Intel)

Hi, 

I don't know whether this is important, but I'd like to know what is causing
this trace message: https://pastebin.pl/view/94557be6 when booting.

Hardware details:
- MB: ASUS M5A97 R2.0
- CPU: AMD FX-8350
- Kernel: 6.1.0
- GPU: Radeon HD 7970 (Tahiti) [Gigabyte GV-R797OC-3GD]

There are no critical problems when using the system. Other than HDMI port not
working anymore (I don't know if this is related. At some point HDMI stopped
working and I've got this message: "drm:detect_link_and_local_sink [amdgpu]]
*ERROR* No EDID read.", which I bypassed using a HDMI>DP adapter).

GRUB command line arguments are: 
amdgpu.si_support=1 radeon.si_support=0 modprobe.blacklist=radeon
amdgpu.vm_update_mode=3 amdgpu.dpm=1 amdgpu.dc=1 amd_iommu=on iommu=pt
video=DisplayPort-0:edid/1204x800.bin

Regards.
