XanMod ships dual kernel releases for Debian and Ubuntu
XanMod has dropped two new kernel builds on the same day, targeting the bleeding edge and the production floor alike. The 7.1.9-xanmod1 mainline release and the 6.18.45-xanmod1 LTS build both landed today. The mainline tree carries roughly 280 patches. The LTS branch sits around 200.
If you run a Debian-based system and care about x86_64 performance, XanMod has been your go-to custom kernel for years. The project doesn't reinvent the wheel. It wraps upstream releases in an LLVM ThinLTO toolchain, layers in aggressive loop optimizations, and offers tiered CPU profiles for everything from Core 2 era chips to Arrow Lake silicon.
What's actually different this cycle
Networking dominates the patch set. Over forty patches tackle SCTP use-after-free bugs, TLS 1.3 retry regressions, XDP accounting gaps, and OpenvSwitch header validation. OpenVPN gets its own security push with eight dedicated patches covering socket ownership checks, zero-initialized sockaddr structs, and peer rehashing logic. Security was clearly the priority this window.
The optimization layer stays consistent. You'll still find Google's BBRv3 congestion control enabled by default, Cloudflare's TCP collapse processing built in, and a dedicated driver module for AMD's 3D V-Cache on Zen 4 and 5 silicon. For gaming, NT Sync primitives emulation and Steam Deck embedded controller sensors round out the patchset.
The rtl8723bs staging Wi-Fi driver actually gets four dedicated patches this cycle. That's right. The obscure MediaTek chip gets a full security pass. If you're running a budget laptop from a few years back, that might matter more than any other change in the release.
The LTS branch carries the same patch count but adds tree-specific adjustments. There's a scheduler accounting cleanup, an IOMMU page table gathering optimization, and a handful of Qualcomm Snapdragon board fixes. It also keeps the real-time variant on life support. The 6.18.44-rt-xanmod1 build dropped back on August 9, which means latency-sensitive workloads still have a home. The mainline 7.1.9 series simply won't see an RT variant this cycle.
Sticking with Debian and Ubuntu, but NVIDIA drivers lag
XanMod continues to support only Debian-based systems. The package list covers Debian bookworm through sid and Ubuntu noble through stonking, with a few asterisks marking longterm support paths. You'll find .deb binaries, source tarballs, and a clean patch file if you want to rebuild the kernel yourself.
Keep in mind that DKMS modules will trail new mainline releases by a few weeks. XanMod maintains companion NVIDIA driver packages at versions 595.91.07 and 610.57.04, both using the open-kernel-module build. Those won't auto-update with your kernel. If you upgrade to 7.1.9 today, you'll want to verify driver compatibility before rebooting.
It's a solid iteration of a niche project. The XanMod team explicitly notes that network stack correctness and security hardening take precedence over new features this window. You'll also notice the deliberate fork between mainline and LTS. The 6.18 branch has until December 2028 to absorb updates, which makes it the obvious pick for servers. The 7.1 branch suits desktop users chasing recent hardware support, though it lacks the real-time scheduler and the same depth of production hardening. Not cheap in terms of development effort, but exactly what the project was built to do.
Head to the XanMod GitLab releases page for the 7.1.9 and 6.18.45 builds. If you're running Debian or Ubuntu, the upgrade path is straightforward. Just don't forget to match your NVIDIA driver before the next reboot.
