When kloading amdgpu, the system panics and the following errors are echoed to the console: [drm ERROR :atom_op_jump] atombios stuck in loop for more than 10secs aborting [drm ERROR :amdgpu_atom_execute_table_locked] atombios stuck executing AD44 (len 428, WS 20, PS 0) @ 0xAE76 [drm ERROR :amdgpu_atom_execute_table_locked] atombios stuck executing A984 (len 158, WS 0, PS 8) @ 0xA9E7 Perhaps there's a tunable I'm missing? Somebody elsewhere suggested setting pcie_gen_cap=0x4 but I'm not seeing how to do that at load-time in FreeBSD.
