Looks like you are still running this without the latest hang fix since i see the deadlock again, but actually what i forgot to ask you is to load amdgpu with vm_fault_stop=2 to freeze the ASIC once VM_FAULT is encountered - sorry about that. So please retest with amdgpu.vm_fault_stop=2 parameter in GRUB loader.
