El recuento de referencias es 0, por lo que el dma_buf se destruye, lo que a su vez reduce el recuento de referencias amdgpu_bo correspondiente a 0, y el amdgpu_bo se destruye. - Se llama a drm_gem_object_release y luego a dma_resv_fini (que destruye el objeto de reserva), liberando finalmente el amdgpu_bo. - nouveau_bo obj-\u0026gt;bo.base.resv ahora es un puntero colgante a la memoria anteriormente asignada a amdgpu_bo. - nouveau_gem_object_del llama a ttm_bo_put(\u0026amp;nvbo-\u0026gt;bo), que a su vez llama a ttm_bo_release, que programa ttm_bo_delayed_delete. - ttm_bo_delayed_delete se ejecuta y desreferencia el puntero colgante resv, lo que genera un fallo de protecci\u00f3n general.
