Hi Juergen,
please find attached a minimal configuration. Note that a kernel
generated with this configuration will not boot, you have to enable
your root block device (ide controller, scsi controller, or serial ata
controller) as well as the root filesystem (ext3, reiserfs, etc...).
You will be missing a lot of things, but at least xenomai should work.

The installation procedure is described in README.INSTALL

Patching with the adeos patch is not necessary before running
prepare-kernel: prepare-kernel is doing it itself. Also, at this step,
watch that the patching runs correctly, that there are no rejects.

Last time I used make-kpkg to generate a kernel package, it ran make
clean before compiling the kernel, which made the kernel compilation
really slow. So, if you want to try many kernel configurations, you
should compile your kernel with make and install it with make install.
Of course, once you have a configuration that works, you can use
make-kpkg to generate a kernel package.

you can also do:
cd /usr/xenomai/testsuite/latency
./run
