This may not answer your question, but apt-get install rtirq-init might be all you need to do in order to get the interrupt priorities set and sorted out for your purposes (well, for sound recording/processing/playback it usually works reasonably well). Even if not, taking a look at what the rtirq service script does might give you good ideas. -- David Kastrup -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
