I went ahead and bought an MSI 370x Gaming Pro Carbon with a Ryzen 7 1700.
I went through quite a few issues installing linux. I tried with Ubuntu 17.04, Fedora 25, and Arch from April, however almost all crashed at some point due to different kernel issues during the install.

In the end, the cause of the issues was the use of the PCIe 16x to 1x riser that I used to connect my Sapphire RX480.
After installing linux, I did some testing, and this issue is present whenever connecting that card through the riser to any of the 1x slots. If I use the riser to connect to the 16x slots, the problem is not there.

Also for testing's sake, I installed Win10, and the the cards work fine using the riser on the 1x slots.

The incompatibility appears to be:
AM4 + PCIe riser on x1 slot + linux

Unfortunately, the board only has 3 full-length PCIe slots, so it leaves me with 3 slots that cause a crash on boot with linux, so they can't be used.

The following does work:
AM4 + PCIe riser on x16 + linux or windows
Intel mobo + PCIe riser on x1 slot + linux or windows
AM4 + PCIe riser on x1 + Ubuntu 17.04 w/ kernel arg acpi=off -> Only one core is visible in /proc/cpuinfo BAD

Unfortunately, I am not finding much info on the topic, probably because the board is new, and on the expensive side for mining purposes.

I am hoping to find a fix before giving up and upgrading my desktop with these parts.

Before anyone suggests differently, just using Window$ is not an option for me, because I am a bit of an open-source zealot.

Hi! i will like to confirm something about this, so you already tested the x370 gaming pro carbon with 6 cards + windows and it worked just fine??? i really need to know this, where i live this mobo would be cheaper than any other option actually for mining, thank you for the testing info already

No, sorry. I only have two cards. The issues I described happened with a single card.

I can confirm up to two cards detected by Windows with risers on the 370x.
