That bug report and https://bugs.debian.org/1001286 do contain the full
history, but it looks like the most interesting/actionable part of that
conversation wasn't shared with upstream.

I have no specific knowledge about this issue, but will try to summarize it.

To which I responded:

The 4 slot limit was specified in 5ace60859e84113b7a185c117fbf2c429d381b59
(upstream commit ID) and the secondary commit message had this:
"Start with just DDR2, DDR3 and DDR4 on x86 for now, and only for systems with
no more than 4 memory slots. These limitations may be lifted later."

That commit by Jean Delvare was from ~2 years ago and it appears that there
may now be a reason to lift/change that limit of 4 (to 8)

As such a change should be discussed (and possibly implemented) upstream,
I asked to forward the request there/here.

Hopefully you now do have the needed information.

Cheers,
  Diederik
