So, there is a problem, likely in your port with CONFIG_PREEMPT, but
maybe in Xenomai (I need to check, because I am not so sure I tested
xeno-regression-test without CONFIG_PREEMPT).
And there is a problem in your port without CONFIG_IPIPE_DEBUG_INTERNAL.
This I do not need to check, I have tested Xenomai wihout this option
enabled.
So, my question is: how do you know the two issues are related?
