i added RAM before to check if it could help running other non-RT

I started 'latency' and then start any perl script. It behavior depends 
on configurations:
     Problematic configuration are:
       1. Kernel 2.6.17.14, Xenomai 2.3.0... r2299, Adeos 1.5-02
       2. Kernel 2.6.19.2, Xenomai r2299, Adeos 1.7-01

     No problems with:
       3. Kernel 2.6.19.2, Xenomai 2.3.0, Adeos 1.7-01
       4. kernel 2.6.17.14, xenomai 2.2.4, Adeos 1.5-00

After applying your patch to configuration #1 or #2 situation become worth:
1) i still get errors,
2) i also get a "Bad pte" with 'process' points to non-RT application 
caused fault
3) sometime perl script "core dumped":
Core was generated by `/usr/bin/perl ./m1.meta.pl U0002323'.
Program terminated with signal 11, Segmentation fault.
