My latency numbers (Intel Atom D2700MUD) are horrible (Base thread 119,168 ns) 
without any modification.  I disabled Hyperthreading in bios and now base is 
19,418 ns after running for an hour or so whilst using the machine.  I still 
wonder if isolcpus works with Xenomai or if there is a different/better way to 
do that?

I assume this won't work since it is based on rtai kernel:
