What you can do is to increase the number of kernels your system keeps. Once that number is reached during installation of a new kernel it removes the oldest one (fifo). This number is defined in /etc/dnf/dnf.conf (installonly_limit=n). Set it to 5, for example.

You can also install older kernels but you want to make sure that you are installing a maintained kernel (still receiving security patches).

If you decide to install an old kernel on your Fedora 23, it can't be a kernel that was compiled for Fedora 22 as you suggest. But it can be the same kernel version, compiled for Fedora 23.

You can get a list of kernel that are in F23 repos here: https://apps.fedoraproject.org/packages/kernel/updates/ Select Release=Fedora23 and Status=stable.

To install them, just run sudo dnf install kernel-4. ... (to see all available press TAB after the 4).

I think those are currently available in stable:

  • kernel-4.2.3-300.fc23.x86_64
  • kernel-4.4.9
  • kernel-4.5.5-201.fc23.x86_64

If some of the recent kernels are not booting your system, you may want to report a bug against the component kernel.
