Hi,


I compiled a fresh rpi-3.8 kernel using the following patches (from
xenomai-2.6.3):
- ipipe-core-3.8.13-raspberry-pre-2.patch
- ipipe-core-3.8.13-arm-3.patch
- ipipe-core-3.8.13-raspberry-post-2.patch

All compiled well, but when booting this kernel it reports an exception.
The entire boot log is here: http://pastebin.com/K7v44nPw

I am still not very faimiliar with the architecture so I am not really able
to sort it myself...
Any advise please?
