Crashes / Instability / Artifacts on 7745HX

Brief summary of the problem:

Seeing some very significant display corruption system-wide on my laptop's integrated graphics. A screenshot I was able to capture is included below. I'm primarily seeing this issue under Wayland, but similar issues with the same dmesg and journalctl messages show up under X11. The log files I've posted were generated when the issue was occurring under Wayland, but I can reproduce them under X11 if it's helpful.

When this issue presents itself, the system quickly becomes unresponsive. Often the display session will crash and restart, restoring functionality, but just as often the system must be fully rebooted.

I saw some threads suggesting that setting ppfeaturemask to 0xfffd3fff might help. If I read this correctly, that suggests to disable stutter mode, overdrive, and gfxoff. I'll try this and see what happens.

Log files (for system lockups / game freezes / crashes)

  • Dmesg:

  • Journalctl:

  • Any other log

    • My OS distro came with the following /etc/modprobe.d/amdgpu.conf file:

      # Force using of the amdgpu driver for Southern Islands (GCN 1.0+) and Sea
      # Islands (GCN 2.x) generations.
      options amdgpu si_support=1
      options amdgpu cik_support=1

      options radeon si_support=0
      options radeon cik_support=0

      From what I understand, that doesn't apply to my situation, but I include it for the sake of completeness.
