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.
