All the processors call the "ia64_monarch_init_handler",
the result is that the same trace appears many times (1 per CPU in fact)
and a kernel oops occurs (I think it is due to a concurrent access
to the same stack without any lock mechanism).

Yes, using Hardware breakpoints. When managing INIT interrupt, SAL calls
the physical address of my function.
