Created attachment 143908 [details] dmesg without patches

Without patches backtrace are looks like initial deadlock backtrace.

Can you please apply back the first 2 patches and then add the following -

Install trace-cmd utility Type sudo trace-cmd start -e dma_fence -e gpu_scheduler -e amdgpu -v -e "amdgpu:amdgpu_mm_rreg" -e "amdgpu:amdgpu_mm_wreg" -e "amdgpu:amdgpu_iv" to enable kernel event tracing log

After hang happens

cd /sys/kernel/debug/tracing && cat trace > event_dump, upload this dump here.
