Yeah, that was nonsense. And I do have a HT-capable test box with an older 2x2 Xeon in fact. It never caused problems, at least not like those you found (the box has sever and unfixable SMI issues, so I stopped using it for Xenomai tests). More ideas: What happens if your run latency like this? taskset -c 1 latency -c 1 Maybe there is some strange issue with sending IPIs on your box (which is required to start things up in case creator and created task sit on different CPUs). If that happens to make a difference, please try again without taskset but with dumping /proc/xenomai/irq before and after the start and post the result.
