well,

there's a bug, and I must admit that I don't know if it's deliberated (*) or 
not.  This bug comes from some time ago. In the /ksrc/arch/x86/patches 
directory, there's a patch for the 3.2.21 kernel:

ipipe-core-3.2.21-x86-1.patch

this patch, in the build process is not included in the root directory: the 
/scripts/prepare-patch.sh script executes:

find $xenomai_root/ksrc/ -name "adeos-ipipe-2.6.*-$supported_arch-*.patch" 

that is incorrect because the ipipe-core* patch is not found. The correct one 
would be:

----------------------------------------------------------------
$ diff -u xenomai-2.6.git/scripts/prepare-patch.sh xenomai-
head/scripts/prepare-patch.sh

so, please could you clarified if you put this patch or not?


(*) Deliberated in the way that maybe it's not sufficient stable yet to 
include it and upstream prefers to not include it by default.

I agree. 

Also, I can mirror the repo at my University.
