Darn, have news: latency thing isn't dead. Two busy loops, one at nice 0 pinned to CPU0, and one at nice 19 pinned to CPU1 produced the latencies below for nice -5 Xorg. Didn't kill the box though. se.wait_max : 10.068169 se.wait_max : 7.465334 se.wait_max : 135.501816 se.wait_max : 0.884483 se.wait_max : 144.218955 se.wait_max : 128.578376 se.wait_max : 93.975768 se.wait_max : 4.965965 se.wait_max : 113.655533 se.wait_max : 4.301075 sched_debug (attached) is.. strange. -Mike
