Hi Serge I need some more info in order to figure out what’s happening, please follow teh steps below: 1. update to latest github code 2. run a fresh boot, with the modules blacklisted as you are doing 3. load the modules, adding the enable_debug=1 param to pf_ring.ko 4. run your application until you are able to reproduce the problem At this point please provide the whole dmesg (before restarting the application, because I need a clean log), and the steps you followed.
Thank you.
