Xenomai can utilize 100% of the CPU, the problem is that if it does so
for a too long time, the system crashes eventually.

I do not understand this question.

Linux as a whole is seen as one task by Xenomai scheduler, executed when
Xenomai scheduler has no other task to execute.

You never showed a test that I could run on my machine to try and
understand what you are trying to prove. And I still do not understand.
Please make a test program, using rt_timer_spin to simulate the cpu
load, and explain me, in very simple word, or with a printf in the test
code, or with a comment in the test code, the problem you observe. Is it
a latency problem?
