I have also successfully verified that -proposed amd64 kernel `6.5.0-7-generic` results in successful network configuration when tested using qemu on an amd64 host with older hardware (ThinkPad T460 with 6th gen intel i5 which is the same hardware which we were able to reproduce the issue on previously). See https://people.canonical.com/~philroche/20231003-mantic-minimal-proposed-kernel/amd64/ for cloud-init logs, some debug output and test image.
