The kernel crashes because it's unable to mount root - I suspect the initrd is not loaded, because I would have expected systemd messages before trying to mount root (after loading additional drivers from the initrd). I assume grub2 fails to load the (now too big?) initrd - you could try compiling out debug symbols and give it a try. What's the size difference between old vs. new kernel and old vs. new initrd? Similar report for aarch64 was at https://bugzilla.redhat.com/show_bug.cgi?id=1615969 which turned out to be a grub2 issue. Which distro/grub2 version etc are you running? -- Thanks, David / dhildenb
