CentOS - Jun 2020 - CentOS 8.2 corrupt pxeboot kernel

Attempting to PXE boot from the BaseOS/x86_64/kickstart/images/pxeboot/ files
results in repeating messages

Invalid or corrupt kernel image

eventually changing to

Could not find kernel image: centos8.2.x86_64/vmlinuz

I downloaded the files again, from a different mirror, and they are all the
same. Wiped the files and recreated /tftpboot/linux-install/centos8.2.x86_64/.
No dice.

First mirror

Second mirror

And it is working here now, too. After replacing the trusty, 8-year old
pxelinux.0 with a slightly newer version. Strange that it should break just
after C8.1.
