I was able to get the hard drive to boot. One major problem was the NVMe drive I tried to originally install the os. It prevented my SSD from loading fully even after I had linux installed. Unfortunately I had to load the os on another computer and then attach it but I was able to load the amd drivers and purge the intel ones. I still want to figure out raid with NVMe on this x399 board. I had to turn on SVM mode and IOMMU on the motherboard in case someone wants to know some of the tweaks. I can’t say if that was the trick but it was what I could find surfing some forums.
Found as solution from the web for the NVME boot freezing issue for Ubuntu users.
1 In GRUB boot menu. press “e” to edit startup parameter ( add commands to boot process) and Add “nvme_core.default_ps_max_latency_us=5500” (the 5500 can be adjusted to meet your system needs) after the phrase “quiet splash” (in the line) and type " ctrl and X" to boot computer.
2. If this is for installation then press “shift” to enter the GRUB again post-installation on reboot. Enter again “nvme_core.default_ps_max_latency_us=5500” after “quiet splash” phrase. “ctrl x” to boot through to log in.
3. Once logged in navigate to “/etc/default/grub” with root privilege and edit “GRUB” file to add “nvme_core.default_ps_max_latency_us=5500” to same spot as above steps and save document. In terminal use command “sudo update-grub” to make change permanent.
I implemented this and was able to add my nvme drives and now they work.
mark this issue as solved and thank you for finding and posting the solution that worked for you!
I am not actually sure how to make the thread solved.
I had problems installing ubuntu 18.04 on ryzen as well, and until they fixed it, i really dunno wether it was a m.2 problem or the ryzen architechture, i installed 16.04 and dist upgraded from there.
It seems my specific is fixed as of 18.04.1 though, dunno if it is related.
I got you bro.
And I’ll mark your one post as the solution.
Edit: wait. This isn’t your thread. :p. Whoops.
