Issue was gone for a while, but lately with Kernel upgrade to Linux 6.8.0-51-generic (6.8.0-51.52 running), system freezes every time after waking up from Suspend mode (mouse cursor freezes, keyboard not active). Sometimes the system also randomly freezes after reboot, with mouse cursor active but not responsive to clicks on shortcuts or keyboard inputs.

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.
