Too few info is provided. I guess this is happening on x86_64. Do you
have the kernel config, and what kernel you are testing? What operation
are you taking to trigger this?

Below commit could be suspect, but not sure if it's the real criminal.

commit 4a693ce65b186fddc1a73621bd6f941e6e3eca21

    kdump: defer the insertion of crashkernel resources

Dave reported a similar one, he did kexec reboot firstly, then in 2nd
kernel crashkernel reservation will trigger the iomem inserting error.

[PATCH] x86/kexec: do not update E820 kexec table for setup_data
https://lore.kernel.org/all/ZeZ2Kos-OOZNSrmO@darkstar.users.ipa.redhat.com/T/#u

Can you try Dave's patch firstly? If it doesn't work, try reverting
above Huacai's patch? it may need manual editing.
