I have built a 2.6.23-rc7 kernel (from Denx git) with Xenomai 2.4-rc3. 
Architecture is powerpc, processor is a 405GP.

I had to make some additions to arch/powerpc/kernel/head_40x.S, and I
can submit a patch if someone tells me where to post it.

    

Here would be nice, or to the Adeos list, indifferently - I would pick
it from both anyway.

  

However, while the kernel boots and runs, the xenomai user apps do not
work correctly.  Specifically, when running cyclictest, I get the following:

    

This patch should fix this issue.

How do I debug this?  I have done a little kernel hacking, but I am a
noob when it comes to Xenomai...

    

Well, actually, it's shame on me. I did not notice that the universal
interrupt controller code was missing some bits in post-2.6.21 I-pipe
patches.
