The same issue persists.
1. I downloaded the kernel-patched with ipipe from the above link.
2. Added the co-kernel using: ../xenomai-3.0.8/scripts/prepare-kernel.sh
--arch=x86_64
3. Made the appropriate kernel config changes.
I have attached my .config file.
To exclude or narow-down config-related issues, you could try starting of with
the x86_64_defconfig, only adding essential Xenomai and board-related switches.
