Most likely a Xenomai bug, the issue does not even happen when changing the affinity, but when binding a new process to the real-time core. I'd say that such core is doing something wrong after noticing the affinity change, which corrupts the kernel state/memory in some obscure ways. -- Philippe. _______________________________________________ Xenomai mailing list Xenomai@xenomai.org https://xenomai.org/mailman/listinfo/xenomai
