Hi Acelan,

The first bad commit:

commit 224dffc89a957e2f006de3202d12c09bf348f992 (refs/bisect/bad)

    drm/amdgpu: make sure to init common IP before gmc

    BugLink: https://launchpad.net/bugs/2000110

    Move common IP init before GMC init so that HDP gets
    remapped before GMC init which uses it.

    This fixes the Unsupported Request error reported through
    AER during driver load. The error happens as a write happens
    to the remap offset before real remapping is done.

    The error was unnoticed before and got visible because of the commit
    referenced below. This doesn't fix anything in the commit below, rather
    fixes the issue in amdgpu exposed by the commit. The reference is only
    to associate this commit with below one so that both go together.

    Fixes: 8795e182b02d ("PCI/portdrv: Don't disable AER reporting in get_port_device_capability()")
