I have two suggestions about how to keep - for a while - the 388 kernel. First - Use DNF to remove the bad kernels. Then when a new one comes in it will take one of those slots. Second - Increase the number of installed kernels. That change is in yum.conf. https://linuxconfig.org/how-to-remove-old-unused-kernels-on-centos-linux If the number is too high, you may run out of room in /boot
