Question Ryzen 3000 'BIOS' fix from AMD for Destiny2 problem...

So just getting news that AMD is rolling out a BIOS fix for Destiny2.

If it's a BIOS fix from AMD that must really mean an AGESA update, as I understand it at least. If so, won't that mean we'll need to be looking for AGESA version later than the current latest, which is ComboPI
This is just really bizarre, and while the details could well be beyond me, I'm REALLY curious as to what, exactly, the problem was and why it caused the issues with Destiny 2, and with those specific versions of Linux.
