--- Comment #1 from coxackie (kostas.kardaras@gmail.com) --- I have the same problem on Alienware Aurora R10 - AMD Radeon RX 5700 GPU. Arch linux, Now at kernel 5.13. I have not "turned on iommu AMDGPU", but there is a crash all the same. The monitor does not get any signal, so cannot turn on after suspend.
logs:
``` amdgpu 0000:0d:00.0: amdgpu: message: RunBtc (58) param: 0x00000000 is timeout (no response) amdgpu 0000:0d:00.0: amdgpu: RunBtc failed! amdgpu 0000:0d:00.0: amdgpu: Failed to setup smc hw!
