Por lo tanto, en modo DMA, iowrite32() en stdev_release() causar\u00e1 un error de p\u00e1gina fatal, y el dma_free_coherent() posterior, si se alcanza, pasar\u00eda un puntero \u0026amp;stdev-\u0026gt;pdev-\u0026gt;dev obsoleto. Para solucionarlo, mueva el apagado de MRPC DMA a switchtec_pci_remove(), despu\u00e9s de stdev_kill(). Contar stdev-\u0026gt;pdev ref ahora es opcional, pero puede evitar accidentes futuros.
