These warning messages should have been fixed in latest kexec-tools since 2017. e820 (/proc/iomem) previously used "reserved", later changed to "Reserved" thus kexec-tools can not recognize. I would suggest you also upgrade to latest kexec-tools, but this should be not harmful since it is still using those ranges as reserved..
