Same as previous question: it seems you booted a kernel without
Xenomai support.

As explained here:
http://xenomai.org/installing-xenomai-3-x/#Booting_the_Cobalt_kernel

When you boot a kernel with Xenomai support, your kernel logs (the
result of running the "dmesg" command, not the persistent ones saved
in /var/log/kern.log), should contain a message about Cobalt being
enabled.
