I'm running Linux Kernel 5.10.9 with those kernel parameters "amdgpu.ppfeaturemask=0xffffbffb amdgpu.noretry=0 amdgpu.lockup_timeout=0 amdgpu.gpu_recovery=1 amdgpu.audio=0 amdgpu.deep_color=1 amd_iommu=on iommu=pt" My graphics card is Radeon 5600XT and i can confirm that this issue still exist :)
Meanwhile i looked at https://lists.freedesktop.org/archives/amd-gfx/2021-January/date.html and there are some patches about ring timeout which i think they aren't yet merged for the next Linux Kernel release. Probably Alex Deucher will merge them later.
