Been happening since 41 update.
All newly installed kernels from updates would always kernel panic, would always have to manually reinstall to get it working. Annoying enough for me to just remove the broken kernels from grub and just get on with my day.
I also asked for lsblk -f output so that I can know what yout disk setup is.
Please provide.
FYI ths is what I have for my f40 kde install for grubby --info=ALL
If you have the default btrfs setup then I think you are missing the rootflags= piece. Also I see that the rhgb quiet has been removed, can I assume something you did to help debug the problem?
