yes. What makes you believe that the lower priority one (prio 135) is chosen? [ as i said before, that will only be chosen if all tasks in the higher-priority queue (prio 105) are either already running on a CPU or have recently run so that the cache-hot logic skips them. ] Ingo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
