Title:
  AMDGPU: Screen frequently and suddenly freezes. Hard reboot necessary.
  AMD Ryzen

Status in linux package in Ubuntu:
  New

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. 
  Linux 6.2.0-31-generic
  Lenovo ThinkPad T14s Gen 1 (with most recent BIOS/UEFI 1.44), AMD Ryzen™ 7 PRO 4750U with Radeon™ Graphics × 16.
