Remove Kernels on Fedora

I’m still running Fedora 31 on my main desktop though Fedora 32 beta has been out for a while. The only reason that stops me from jumping to F32 now is because ZFS 0.8.3 is not compatible with the kernel 5.6.* on F32. Rumor has it, ZFS 0.8.4 will support kernel 5.6. Tonight, while doing the system update with sudo dnf update -y on F31 desktop, I noticed that the kernel for F31 is now kernel-5....

Gentoo Luks Fails Kernel 5.6

My Gentoo based Linux laptop which is still running the older kernel 5.3.15. A short while back, I had a failed attempt to upgrade the kernel to 5.4.2 as the disk which encrypted with dm-crypt couldn’t be decrypted on boot.
