>Description:

My machine has a 041:00:0: ATI Technologies Radeon RX 470/480/570/570X/580/580X/590 (VGA display, revision 0xc7)
041:00:0: 0x67df1002 (0x030000c7)
graphics card.

When enabling amdgpu in the kernel config (and firmware building for it),
I get a kernel fault at init time:

It crashes in:


ttm_bo_validate+0x11a
0xffffffff811da570 is in ttm_bo_validate (../../../../external/bsd/drm2/dist/drm/ttm/ttm_bo.c:926).
921	void ttm_bo_mem_put(struct ttm_buffer_object *bo, struct ttm_mem_reg *mem)
922	{
923		struct ttm_mem_type_manager *man = &bo->bdev->man[mem->mem_type];
924	
925		if (mem->mm_node)
926			(*man->func->put_node)(man, mem);
927	}


ttm_bo_init_reserved+0x35a
0xffffffff811da908 is in ttm_bo_init_reserved (../../../../external/bsd/drm2/dist/drm/ttm/ttm_bo.c:1395).

0xffffffff8090d4ec is in amdgpu_bo_do_create (../../../../external/bsd/drm2/dist/drm/amd/amdgpu/amdgpu_object.c:585).


Unfortunately I couldn't get a crash dump.
