Use `eselect kernel list` : it will show which /lib/modules it will go to (as an example here's mine): $ eselect kernel list Available kernel symlink targets: [1] linux-4.1.37-gentoo * [2] linux-4.9.16-gentoo If I merge a package with kernel modules, it will currently go to lib/modules/4.1.37-gentoo, which is what my kernel symlink is set to. You can use `eselect kernel set` to change this symlink. In my case, using `eselect kernel set 2` will change it to 4.9.16. In your case, list the installed kernels and set it to the new kernel and `emerge -a @module-rebuild` and you'll be good to go. Dan
