--- Comment #2 from Alex Deucher (alexdeucher at gmail.com) ---
The trace is related to this option:
amdgpu.vm_update_mode=3
You should remove that.  In fact the following parameters shouldn't be needed:

amdgpu.vm_update_mode=3 - this should only be used for debugging GPUVM related
problems.

amdgpu.dpm=1 - this is the default

amdgpu.dc=1 - Does removing this fix the display issues with HDMI?

amd_iommu=on iommu=pt - IOMMU is enabled by default on most distros IIRC.

video=DisplayPort-0:edid/1204x800.bin - You shouldn't need this if the displays
are detected correctly.  Does removing amdgpu.dc=1 fix this?
