With the "RT-abuse" hang, this 30 second thing goes on hold (because it's done from those kernel threads that cause you those hickups in sound :-) and you can starve a far longer period of time.. which may well mean a far larger dataset not hitting the disk. - 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/ | ||||||||||||
