I am having problems installing Ubuntu 18.10 in my system. I was trying to install ubuntu Budgie flavor but that is where my problems started and then I tried the original ubuntu 18.10 and it gave me the same problem I have done it in UEFI and bios mode and in both it has given me the same problem.

My system Specs are:

  • Motherboard - Gigabyte AB350M-DS3H
  • CPU - AMD Ryzen 5 2400G
  • RAM - Timetec 2400mhz 16GB
  • Graphics - XFX Radeon RX 560

The problem is that every time it boots into installing directly or live boot they both hit me with a Fatal Error that indicates that the kernel panic, one time it gave me a reason which pointed out that the init wasn't found.

When it first starts up it runs AMD-VI completion-wait loop timed out before the error pops out.

I already tried running the installation with the integrated graphics card as suggested in another thread, but it gave the same error.

Final Edit: I have given up on dealing with linux for now. This hardware doesnt support a stable linux experience at all. After IOMMU being disabled and the instalation finishing a lot more problems occur like screen stutering which I had to install amdgpu-pro to get it to stabalize, vulkan wont work even when installed properly says it can't load "radeoni". There is also a performance hurdle, but I don't believe its linux fault but AMD's poor linux support.

In the future I'll build a new machine around Linux and will most likely just go intel+nvidia.

You have to disable IOMMU in BIOS for the errors to get fixed.

I had trouble with Ubuntu but never understood what was the problem until I ran Manjaro and that distro gave me more insight into my error by mentioning a problem with IOMMU AMD V. And so I went to BIOS, disabled IOMMU and both Ubuntu (any version) and Manjaro booted into their live session. Of course, I don't know if it can be installed yet or how well it will respond after installation but I finally was able to boot into the live distro which is good progress.
