I recently upgraded to a Ryzen 5 3600, Asus Rog Strix B550, 32GB DDR4 3200 Mhz, 2x Samsung EVO Plus 970. My plan is to have Windows 10 on its own m.2 while Ubuntu is on my second m.2. (Windows 10 is already installed) When I boot the live USB to install Ubuntu I am greeted with a screen of errors.

I have tried updating my BIOS to the latest version. I have Fast Boot, CSM and virtualization disabled.

Most of it is AMD-VI errors and then the PC just freezes up. My old build (Ryzen 5 1600) I had no problems dual booting. Does Linux have issues with the new Zen CPUs? I am kind of at a loss here since I really need this up and running asap.

  • If you have csm disabled (UEFI enabled) then you need to prepare USB stick in UEFI mode. Rufus can do that. – Michal Przybylowicz Aug 7 '20 at 23:52
  • I should of noted that my usb stick is already in uefi mode. – Blake Rambo Aug 8 '20 at 0:02
  • Have you updated UEFI and SSD firmware? Asus ROG Strix B450 E motherboard UEFI update worked askubuntu.com/questions/1174679/… – oldfred Aug 8 '20 at 3:31
  • @oldfred isnt UEFI and SSD firmware the same thing as the bios update? I have the latest BIOS update. – Blake Rambo Aug 8 '20 at 4:17

    Some with other brand motherboards, but same AMD chip have needed IOMMU changes. turns out the IOMMU needs to be enabled in the BIOS. This problems seems to be exclusive to AMD boards. And then perhaps this: GRUB_CMDLINE_LINUX="iommu=soft" But this user just installed & it worked. Asus tuf gaming x570-plus ubuntuforums.org/showthread.php?t=2445883 – oldfred Aug 8 '20 at 18:13

This comment worked for me:
