--- Comment #7 from Nicolai Hähnle (nhaehnle at gmail.com) ---
VRAM buffers can get split into multiple underlying memory chunks; in this
case, bo->mem.start == AMDGPU_BO_INVALID_OFFSET; it's not a logic bug.

bo->offset is only used via amdgpu_bo_gpu_offset, which has a WARN_ON_ONCE to
guard against accidental use of the field in this particular case.

Therefore, I'm inclined to say that this is probably not an actual bug.
