Small update: I've applied the settings mentioned here: https://community.frame.work/t/tracking-hard-freezing-on-fedora-36-with-the-new-12th-gen-system/20675/146 This seems to avoid freezes without an external monitor, but freezes still happen when an external monitor is connected. It doesn't matter if HDMI or USB-C. I'll try the nomodeset boot option now and check if that helps. Regards Daniel
