I have tried that actually and it didn't work in my case (outside of your contrived scenario [1], though forcing a full modeset should take care of that case regardless). Though, I strongly suspect a firmware hang with the issue that I'm seeing since I get DMCUB errors before the timeout. i.e.: amdgpu 0000:06:00.0: [drm] *ERROR* dc_dmub_srv_log_diagnostic_data: DMCUB error - collecting diagnostic data [...] amdgpu 0000:06:00.0: [drm] *ERROR* [CRTC:364:crtc-0] flip_done timed out [1] https://lore.kernel.org/r/[email protected]/
