Details
The core systemd package back-ported a fix for bad RdRand
behavior on the new AMD Zen2 processors. The 2019.07.01
installer will not boot on Zen2, but making your own with
archiso with the latest systemd from core works fine. It
might be nice to get a release out there so that people with
the new processors don't need a second computer to build the
installer.
The version of systemd that would need to be included in a release to get a fix out for these users is 242.32-3. |

Upstream systemd issue that was worked around: https://github.com/systemd/systemd/issues/11810
Ryzen 3xxx review from Phoronix that mentions this issue, showing that there are people that could benefit from this: https://www.phoronix.com/scan.php?page=article&item=ryzen-3700x-3900x-linux&num=2
I also confirmed this myself with a Ryzen 3900X + X570 motherboard. Packaging my own installer with the updated systemd makes it work again.
Thanks for all the work you guys put in!
