Thanks for this clear summary. I have some more questions and things for you to do please: Please post the more detailed report of the unexpected delays which is in dmesg. Please copy the report exactly. If you can cause a few of them on different runs of EMC2 and post them it will help us understand what is happening. Also are you using the magma kernel from the emc2 repository or did you build your own? I ask because speed scaling is disabled in the emc2 magma kernel. Have you run the rtai kern/latency test for a while on a loaded system, and if so, what are the results after a long run? Please post that information too, copy a line from the results after a long run. Do you have another video card that is not nvidia that you could try?
