Hi everybody.

I'm working with an Apple Powerbook 15" G4, Xenomai 2.1 (SVN), Linux kernel
2.6.14.3. I'm using Umbutu 5.10 with gcc 3.4.5

simone@domain.hid:~$ gcc -v
Reading specs from /usr/lib/gcc/powerpc-linux-gnu/3.4.5/specs
Configured with: ../src/configure -v
--enable-languages=c,c++,f77,pascal,objc,ada --prefix=/usr
--libexecdir=/usr/lib --with-gxx-include-dir=/usr/include/c++/3.4
--enable-shared --with-system-zlib --enable-nls --without-included-gettext
--program-suffix=-3.4 --enable-__cxa_atexit --enable-libstdcxx-allocator=mt
--enable-clocale=gnu --enable-libstdcxx-debug --disable-softfloat
--enable-targets=powerpc-linux,powerpc64-linux --with-cpu=default32
--disable-softfloat powerpc-linux-gnu
Thread model: posix
gcc version 3.4.5 20050809 (prerelease) (Ubuntu 3.4.4-6ubuntu8)

I have two residual problems:

1) The machine is unstable (freeze after a while) if Xenomai FPU support in
the kernel is active. This is a know problem. Gilles help me to find the
catch and complete the installation. The problems is related to the Altivec
unit present in the G4. I tried to fix the problems eliminating the  Altivec
support (in the kernel coinfiguration) without success.

2) If I activate the interrupt shield in the kernel, the kernel compilation
stops this this message:
