Pratheesh helped me make a patch against the latest linux-omap git to
try this.
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...
