Detailed follow-up in the bug report, but for anyone following along
here, I think this was caused by changes to the set of scripts in
kexec-tools between F38 and F39 which have the effect that a
crashkernel= arg will almost always get added whenever a kernel is
installed, or kexec-tools is updated. Previously that was not the case.
