I have been using 2.6.0-test3-mm3 plus O18int for a whole day and I mustI'll second that, the priority inversion issues I was having with 2.6.0-test3-mm2 are completely gone! I haven't been able to get any serious inversion issues to bring the system to its knees yet, but I'll keep trying. The only difference is that I've disabled sound in order to use the latest kernels, but I don't think that probably had anything to do with the inversion problems I was running into.
say that, for me, O18int is the best I've seen until date. I dare to say
I think it's even better than O10int.
