Hi Mathieu,
I apply the patch by Xenomai latest stable v3.0.1 to my RPI2, and
sometimes the booting hang like this:
 * Starting configure network device security[ OK ]
 * Stopping load modules from /etc/modules[ OK ]
 * Stopping userspace bootsplash[ OK ]

That's low probability, about 1 of 60 times booting, and the original
not patched kernel is OK.
The kernel is the latest version from
https://github.com/raspberrypi/linux/tree/rpi-3.18.y .
First, I apply the ipipe patch "ipipe-core-3.18.20-arm-6.patch" from
https://xenomai.org/downloads/ipipe/v3.x/arm/ . Then I apply your RPI
patch version #5. The kernel is build follow this instruction
https://www.raspberrypi.org/documentation/linux/kernel/building.md .
The root file system is Ubuntu 14.04 LTS for RPI2, which from
https://wiki.ubuntu.com/ARM/RaspberryPi .
Attached is the kernel booting hang log file and kernel config file.
What can I do to get more infomation for debugging when kernel booting hang?
Look forward to your reply.

Joe Lee
