As far as I understood, Adeos version does not matter for your bug,
what matters is xenomai revision. So, during your tests, you should keep
the same Adeos version and only change Xenomai version.
However, if you have difficulties with some versions of Adeos, you
should report the errors here. We are interested in getting them
solved.

I see that you you have selected the K7 processor. Be sure to use an
Adeos version greater than 1.5-02, or select a processor that does not
support 3DNow (I think K6 should do).

If revision 2299 of branch v2.3.x fails, you should stay in branch
v2.3.x. Try revision 2150, if it fails, try revision 2075, if revision
2150 works, try revision 2225, etc... Do not forget to rebuild kernel
and reboot between tests. And tell us when you have found that revision
n works and revision n+1 does not work.
