Hmm this is for SMBIOS tables that changes at runtime?
Why exactly is the kernel booting a good point to dump that?

Normally the kernel afaik doesn't change SMBIOS as far as I know.

There may be some hotplug events that change it, but they
have no particular relation to kernel boot.

What information exactly?

And dumping = print to system log?

Like what?
