7.0 is already present in forky (current testing), and available as a backport for trixie (current stable):
* https://packages.debian.org/search?keywords=linux-image-amd6...
* https://packages.debian.org/trixie-backports/linux-image-amd...
The default kernel for trixie/stable is 6.12, initially released in November 2024, and officially supported upstream until December 2028.
I wish more people would consider Debian for their devices. It is a very stable system, which I appreciate, and, unlike Ubuntu, it was really an "it just works" experience, without any of the friction points that smaller distros have. I installed Debian Trixie on a very recent device (granted, all AMD for compatibility) when Trixie was still the Testing version, and all the necessary drivers were present.
Now if only I could figure out how to build packages and contribute back to Debian... Also if only AMD could get their NPU support for Linux figured out...
If you don't actually need all the drivers, you can use "make localmodconfig" to substantially reduce that. My local kernels build in 90 seconds on a 32-thread desktop machine :)
The kernel is a lot more stable than people think: I run the daily linux-next on my Debian stable gaming PC to look for bugs, and I don't find very many.
The resources behind your post likely have a larger carbon footprint.
The last time I worried over which kernel was used in Debian Stable was... never. If I want a more recent kernel I run Debian unstable (Sid) which currently is at 7.0.12 (the current 'stable' kernel where 7.1 is 'mainline') but on my servers Stable (currently 'Trixie') does just fine with its 6.17.3 kernel. Debian 'Forky' will be released somewhere in 2027 with either a 7.0.x or 7.1.x kernel depending on how things go. The current kernel used in 'testing' (which will become 'stable' on the next release) is 7.0.10.
To do so, add the sources for trixie-backports and unstable, and add the following configuration (e.g. /etc/apt/preferences.d/trixie-sid-pin) so that the system knows which sources your prefer:
# Default to trixie
Package: *
Pin: release n=trixie
Pin-Priority: 990
# Very low priority for sid
Package: *
Pin: release n=unstable
Pin-Priority: 100
# Give backports medium priority
Package: *
Pin: release n=trixie-backports
Pin-Priority: 500
Now the system can access the latest kernel from unstable (and backports), while keeping everything else on stable: # apt policy linux-image-amd64
linux-image-amd64:

I believe the kernel in backports gets updated only after it is live in unstable for at least a week, which lately still feels like forever.
