Ok, but there are many branches here, could you check whether it emits
the syscall, and if yes, what is the result of this syscall?

It confirms that the option is enabled in the kernel you compile, not in
the one you run...

By standalone, I meant without RTnet. So, please verify that you also
get the bug without RTnet, and post a mail to the Xenomai-help mailing

It would be nice if you could check whether the latest 2.4 release (that
is 2.4.10), if it is not the one you are using currently. Also, you do
not tell us on which architecture you have that bug.
