Hard reboot necessary. AMD Ryzen Status in linux package in Ubuntu: Confirmed Bug description: Frequently, when I just use the computer, the mouse cursor freezes, the screen starts to flicker and freezes (screen flickers between entirely black and desktop visible). No interaction possible. In most cases Ctrl-Alt-Prnt-REISUB works to hard reboot the system. Frequency: Freezes happen several times a day. Unsaved work is lost. I noticed that: * The freezes usually happen when an external display is connected (it does not matter whether USB-C or HDMI). The freezes rarely happen when no external display is connected. * The freezes happen with Wayland and X11, with Ubuntu UI and Gnome Shell. * The freezes happen randomly, but I have the feeling that they happen more often when "something graphical" happens, e.g. when I go to the Gnome Shell overview, desktop switching, or when I switch to/from full screen mode, click on an image to scale it, or when I use map services in the web browser like Google Maps or radio.garden. * The freezes even more often happened when WebGL is active in Firefox or Chomium. * I encounter these annoying freezes already for several weeks. Having looked at the log files, I assume that AMDGPU is at the core of the problem. System: Ubuntu 23.04 (up to date), Wayland (freezes also happen with X11), Gnome 44.3.
