thanks for reply.
Checking the folder Xenomai ...

root at debian:/usr/local/buildroot-2011.11-rc3/output/build/xenomai-2.6.0/ksrc/arch/arm/patches#
ls
README
adeos-ipipe-2.6.35.9-arm-1.18-03.patch
adeos-ipipe-2.6.38.8-arm-1.18-04.patch
adeos-ipipe-2.6.37.6-arm-1.18-03.patch

You mean I can only use these three kernel versions?
The configuration file (qemu_arm_versatile_defconfig) is kernel v3.1. I
have no way of putting it compactivel?

Yes.

You must change v3.1 to v2.6.37.8 (easy solution) or you have to port
Adeos over to v3.1 (difficult solution).
