This fell through the cracks for me. Can you please provide your DLC configuration. |

Amir, just create (export) DLC configuration with few numbers of CPTs and then reduce the count of them and try to load previous DLC configuration. For example, create DLC configuration with cpu_pattern="" and then try to load it with cpu_pattern="N" |

Question: when you configure the CPTs in modprobe and you change cpu_pattern as you mentioned, is it handled differently? or do you have to match the network CPT configuration in the modprobe configuration as well? |
