At first sight, you call spin_lock_irqsave in __ipipe_mach_set_dec. This is illegal, __ipipe_mach_set_dec may (and will) be called from real-time context, you should be using the _hw variants. I do not know if it is what causes the oops, but it would cause an oops later. -- Gilles _______________________________________________ Xenomai-core mailing list Xenomaiemail@example.com https://mail.gna.org/listinfo/xenomai-core
