Public bug reported: System boots OK from USB install and shows the screen in 4k on my iiyama monitor.
But after installation it just hangs with a cursor at the top left of the screen. So after editing grub with "nomodeset" it then boots with this error (no UMS support in Radeon module) then boots into the desktop at a fixed 1024x768..
