Attached are the diagnostic files referenced in my original report. They include:
- kernel logs from the affected 6.12.85 kernel with amdgpu.dc=0 - comparison logs from the working 6.12.74 kernel - PCI and driver-binding information - DRM-node information - package, BIOS, and system details The important comparison is: - 6.12.74 with amdgpu.dc=0: amdgpu binds and UVD initializes successfully - 6.12.85 with amdgpu.dc=0: the UVD v6 ring test times out with -110, and amdgpu probe fails No manual rebind was attempted in the attached affected-kernel boot log.
