Liquorix drops linux-liquorix 7.1-10, re-applies TTWU wakelist patch
The new build is anchored on upstream Linux 7.1.8 and ships with a scheduler tweak aimed at cutting latency spikes.
Steven Barrett has pushed linux-liquorix 7.1-10 to the Liquorix repository. The package is built on top of upstream Linux Kernel v7.1.8 and signed with the maintainer's verified GPG key. If you're running Debian or Ubuntu and you care about deterministic latency, this is the update to grab.
Liquorix isn't your typical stable kernel. It's a community project tuned for desktop and workstation workloads where predictability matters more than raw throughput. The latest build pulls in the full 7.1.8 stable update, but the real headline is a scheduler change that has been bouncing around the codebase for a while.
The changelog lists three straightforward items. A straight merge of v7.1.8. A version bump to 7.1.8-1. And a re-application of the TTWU wakelist disable patch. That last change is where the project actually earns its keep.
The "Try To Wake Up" scheduler path optimizes how tasks transition from sleep to runnable by deferring runqueue migrations across per-CPU queues. On paper, it's efficient. In practice, it tends to introduce unpredictable latency under gaming or real-time audio video workloads. The wakelist mechanism works great for server farms. It gets jittery on a desktop pushing audio through Jack.
By reverting that code path, the kernel favors simpler wake up mechanics. You get lower worst case latency and fewer cache thrashing migrations across cores. It's a rather expensive machine for the internals it is touting, though the design and small form factor do help it somewhat. Wait, that last line was a stray thought. The point is simpler: Liquorix trades theoretical average case throughput for tighter latency bounds.
The commit message includes "again" for a reason. This exact scheduler toggle has been a recurring debate in kernel circles since it first landed in mainline. Some distros keep it enabled for bulk throughput. Others, like Liquorix, keep turning it off when it starts hurting interactive responsiveness. It's a pendulum that never quite settles, and Barrett has been fine tuning it for years.
Upstream 7.1.8 Brings the Usual Stable Package
Linux 7.1.8 is an incremental update on top of the 7.1 series. You're getting security patches, newer CPU enablement, and driver improvements across GPU, networking, storage, and USB subsystems. It's refinement rather than a feature overhaul. If your hardware already works in 7.1.x, this update is mostly about the scheduler patch and the latest security backlog.
Keep in mind that the build runs through a Docker based pipeline. The system parallelizes across architectures, though AMD64 is currently the only supported target. That's a minor limitation if you're on ARM, but it keeps the Debian and Ubuntu packaging loop tight. The repository also carries 350 stars on GitHub, over 4,000 commits, and a GPL 2.0 license.
Installation and Verification
If you haven't added the Liquorix APT source yet, you will need to drop the keyring and repository line into your system before pulling linux-headers-liquorix and linux-image-liquorix. The process is straightforward and documented in the upstream README.
The release is verified against GPG key 9AE4078033F8024D. Verify that signature before booting if you're rolling your own config. It takes thirty seconds and saves you from tracking down a compromised package mirror later.
Getting the kernel is straightforward. The official install script pulls Debian, Ubuntu, and Arch builds:
curl -s 'https://liquorix.net/install-liquorix.sh' | sudo bash
