I'm wondering what this message actually means. "Unexpected hw_pointer value"?
Does this actually indicate an underrun, or is the debug code screwy? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
