I did not install any specific driver, I probably use the standard Trident
driver that came with the Kubuntu distribution.

Ok, I installed Xenomai 2.2 from scratch over a freshly extracted kernel
source tree, used the tracer patch ipipe-tracer-2.6.17-i386-1.3-08.patch,
rebuilt the kernel and relaunch the test : I still get increasing latencies.
I attach a copy of the latency test run, and the associated traces in
files "max" and "frozen" from /proc/ipipe/trace
I have no clue how to interpret theses traces, is there a documentation/user's
guide available for the ipipe tracer ?

No, I don't get any of these.

I tried to rebuild with CPU=486, but it gives the same result.
