Sorry for the mistake,

I'm not getting results with ltp, I mean I get the same as before.
I wanna try hackbench a few hours, I followed this post:
http://www.mail-archive.com/xenomai-help@gna.org/msg14194.html

I tried hackbench only with dohell:
root@labcontrol:~# /usr/xenomai/bin/dohell -b 
"/home/labcontrol/Downloads/ltp-full-20120903/testcases/kernel/sched/cfs-scheduler/hackbench

And with xeno-test:
root@labcontrol:~# /usr/xenomai/bin/xeno-test -l "dohell -b
