One of the suggested work-arounds in that bug report is to revert to an older version of dracut and rebuild your initrd. You'd need to get: dracut-033-535.el7.x86_64.rpm dracut-config-rescue-033-535.el7.x86_64.rpm dracut-network-033-535.el7.x86_64.rpm kexec-tools-2.0.15-13.el7.x86_64.rpm ...from the vault: http://vault.centos.org/7.5.1804/updates/x86_64/Packages/ Downgrade those packages, and then run "dracut -f" to rebuild the initrd for your kernel.
