With this patch, my IRQ -33 problems with the DSP have disappeared. Before, I would end up in IRQ -33 loop after 10 invocations of the DSP Bridge 'ping.out' utility. I just finished running it 50,000 times without error. As stated before, this patch is just a workaround for testing purposes, not a fix. Who knows what performance side effects it has...
