[SOLVED] Unable to get Xorg to work on Thinkpad E585

I just got my new Thinkpad E585 laptop, and I've spent today trying to set up Arch and restore my i3 setup from a previous computer. This isn't my first time installing Arch, and after applying the kernel parameters mentioned on the wiki, it went fairly smoothly. The majority of my time has been spent trying to get xorg to work. When I initially started trying, it would just hang there and not offer any feedback. Checking the log for that period, it initialized successfully but didn't draw anything to the screen, left no trace as to why. Now I'm trying to just get twm with startx working and the problem has changed, Xorg seems to start up, the screen blacks out of the TTY that I've been operating out of, and then it starts filling up with log messages about a hardware error. It never kernel panics, but I have to force power off my computer at this point. I snapped a picture of some of the log output from journalctl, but overall the messages spammed were what I captured repeated over and over again.

Environment:
Lenovo Thinkpad E585
AMD Ryzen 5 2500U with AMD Radeon Vega 8 gfx
Linux 4.20

Sorry for the oversized image, as I had no GUI I didn't think of a way to get the journalctl output onto a paste site. Also, after some googling after posting this question with the specific error message, I found the bugzilla link, and the iommu=soft solution seems to have worked. Thanks!
