My laptop is behaving suspiciously (resume from sleep sometimes fails).
The problem first happened on kernel
4.8.10-200.fc28. But this is the oldest kernel I still have installed. I only have the most recently 3 Fedora kernels installed.
(This is despite me having set
/etc/dnf/dnf.conf over 6 months ago, in an attempt to keep old kernels around for longer. It seems that PackageKit (or the backend for libdnf) is just broken.)
Is there a quick way to install older kernels for testing purposes? (And is there any way to avoid them being removed automatically, when the next kernel update happens?)
