That, or just pick the kernel package from unstable or testing. Apt is smart enough that mixing packages from different versions of Debian works just fine.

(I mean nothing is 100% but I've been mixing packages for like 2 decades now and literally can't remember any specific trouble resulting from it.)

While I won't deny that this may often work, I disagree that it's a good idea, and that `apt` being smart is sufficient to guarantee that this works (or keeps working in the future).

Pinning specific packages from `testing` or `unstable` is explicitly discouraged, for very good reasons covered by this classic link: https://wiki.debian.org/DontBreakDebian#Don.27t_make_a_Frank... .

Arguably, the backports kernel is the right choice to get a newer kernel on Debian Stable. Indeed, in the past, the backports kernel could take awhile to update, but no more - case in point, `trixie-backports` currently contains `7.2`, same as `unstable`.

It's not apt not being smart that can cause troubles when mixing packages from various suites. There's no reason to mix in cases where you can just use backports instead.
