No, the solution is to lock the interrupts onto one specific processor and don't move it around. That's what's causing all of the problems. And you can enforce this policy now in the driver even if just for testing by calling the set_affinity() interfaces on the interrupts your driver has. You can even walk over the cpu_online_map and choose a load distribution of your liking. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
