kdump will make sure of purgatory too. And there does not seem to be
any logic which verifies the checksums of loaded segments hence reducing
the reliability of kdump operation.

So I think fixing the purgatory part here is a must. It leads to better
design as well as improved reliability for kexec/kdump operations.

Thanks
Vivek
