OK. Here goes my fresh and newly jack_test4.1 test suite. It might be

Thanks

Here's fresh results on more stressed hardware (on ext3) with 2.6.11-rc1-mm2 (which by the way has SCHED_ISO v2 included). The load hovering at 50% spikes at times close to 70 which tests the behaviour under iso throttling.
