They just merged: ( ) No Forced Preemption (Server) ( ) Voluntary Kernel Preemption (Desktop) ( ) Preemptible Kernel (Low-Latency Desktop) So for a full preemptible DAW kernel you'll still need ingo's patch applied. btw i had the same experience with 2.6.12 and RT... horrible stability, not faster in any way as vanilla+normal preemption. The best so far is 2.6.11.x + rt, 2.6.13-rc6 is quite stable here, but i use it w/o RT and am back on Con Kolivas -ck2 with new improved SCHED_ISO and very pleased with it so far. But for a production DAW i would use 2.6.11.x + ingo's RT. Regards Tom -------------- next part -------------- A non-text attachment was scrubbed...
