Either the kernel badly misses unwinding information, or you have a real build problem pending. Try enabling CONFIG_DEBUG_KERNEL if not already done to get full backtracing support, and don't forget to reinstall all modules if any. > Unfortunately I have no idea, what causes this oops. > Is there anybody that has some hints on this oops? It's always more efficient to compile all Xenomai support statically into the kernel instead of using modules when debugging: virtual address mapping to symbolic info is much easier. -- Philippe. _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
