Yes, a stable tag is needed. vulkan guys say 5.14 hit this issue too.
I think that amdgpu_bo_move() does support copy from sysMem to sysMem correctl
Yeah, but that should never happen in the first place.
Even when the BO is on the wrong LRU TTM should check that beforehand.
In other words when we pick a BO from the LRU we should still double
check bo->resource->mem_type to make sure it is what we are searching for.

maybe something below is needed.
