Drivers compiled for particular kernel versions do not load on other kernels.
Thus, you need to get a new compiled driver from Leopard Imaging, or you need to get the source from them and re-compile it yourself, assuming it’s been ported to the new kernel version.
This is a significant difference between industrial Linux systems like the TX2, and mainstream Linux systems like a typical desktop/laptop/server – the latter have all kinds of plug-and-play hardware interfaces that makes integration easier; the former don’t, and need various “hard-coded” driver set-ups.
