Yeah, I realized that as well after sending the first mail.
The problem is that we keep the bulk move around when there currently
isn't any resource associated with the template.
So the correct code should look something like this:
if (fbo->base.resource) {
ttm_resource_set_bo(fbo->base.r
Inside the function ttm_bo_set_bulk_move, it calls
ttm_resource_del_bulk_move to remove the old resource from the bulk_move
list.
If we set the bulk_move to NULL manually as suggested, the old resource
attached in the ghost BO seems won't be removed from the bulk_move.
