@nina_kali_nina @mcc Also, Linux-CIP works on a heavily restricted set of industrial-grade hardware; if you're not a sponsor, your machine very likely isn't supported.
For instance, Linux 4.4 on CIP only works on two architectures (can't remember which) and only on specific hardware.
It's meant for big actors (like the railway or medical industries) who absolutely cannot upgrade the kernel beyond mandatory security patches because of certifications/safety constraints.
