So I suppose that the patch for 2.6.19 is finished. I've tried it and it works fine. The result of latency is :

Is it realistic ? Now, the port to 2.6.20 is open ? we can work on ? trem _______________________________________________ Adeos-main mailing list [email protected] https://mail.gna.org/listinfo/adeos-main
