Well, Roland, you once again picked the non-common approach for your first setup, so you _have_to_ expect uncommon problems. You said that building and installing your own clean vanilla+xenomai kernel from scratch is so much more complicated - do you expect me to seriously comment on this anymore? We had the same discussion not long ago when you started to get your feet wet with Xenomai. >> If so, and I do want to get this running what is the advice? Start >> trial and erroring with any and all kernels I can lay my hands on to >> see if there is one out there that is actually compatible?:) Try a >> couple of other distros? Anything?.........damn. Please just do what everyone does _first_, do something that _we_ can easily reproduce. If that fails we will be quickly at your site because the effort/result ratio will be far better than now (or order individual support). _Once_ you have a standard setup working, going the winding road is still an option and would _far_ better reveal where RTnet or your steps have a problem. If you go a non-standard path like now, we depend on _you_ to find the common ground, the differences, and then the reason for this issue. > > Help yourself, try finding the problem.

Though I'm afraid the result will just once again tell us something is missing, and as we cannot reproduce your kernel tree, we will be not much wiser than before. Jan
