You mean the standard latency test?

I-pipe 2.4.25/ppc 1.2-01?
Which kind of board?
Which Xenomai version?

Let's try a simple setup with your environment if it is not already the
case: Xenomai 2.3.1 stock + 2.4.25-ppc 1.2-01, standard latency test in
user-space. If you could also boot and run your current kernel on a
vanilla glibc-based ELDK setup (likely 3.1.1 with 2.4/ppc kernels), we
could check whether busybox raises new issues or not. The latest setup
works perfectly fine here on an Icecube for instance, "yes" and
"netstat" tests included.
