Yeah, thanks! That's exactly what I needed.

And my initial suspicion was right, for some reason we try to free the SG t=
able
twice:

[  141.833287] [drm:radeon_ttm_backend_unbind [radeon]] *ERROR* ttm->sg =
=3D
ffff880222930e00, ttm->sg->sgl =3D ffff8802238bd200
...
[  141.898159] [drm:radeon_ttm_backend_unbind [radeon]] *ERROR* ttm->sg =
=3D
ffff880222930e00, ttm->sg->sgl =3D           (null)

Which then obviously causes problems.

For a quick fix we could try to double check if we haven't already freed the
table, but I think the underlying problem is that we try to free the BO twi=
ce
as well.

@Michel any ideas?
