@evercoast-smm hello,
The kernel patch for 4.16 was developed with Xenial distribution:

./scripts/patch-ubuntu-kernel-4.16.sh: line 106: ../scripts/realsense-camera-formats_ubuntu-bionic-v4.16.patch: No such file or directory

In general only Ubuntu LTS kernel patches are maintained. (4.4, 4.15, 4.18..). Is there any particular reason to use non-LTS kernel with Ubuntu 18?

[evercoast-smm]

Thank you. We've moved onto 4.18.20-041820-generic.
