However, I would like to point out that Debian version numbers differ from the kernel version, which is merely one component of the system. Please refer to /etc/debian_version and /etc/os-release to determine the version of the distribution you are running. The current kernel version for Debian 12, codename "bookworm", is 6.1.129-1. The 4.9 kernel was in Debian 9 "stretch", which is quite outdated, and many relevant components have been updated since, so even with "exactly the same configuration layout", you can expect different behaviour.
