To Reproduce Steps to reproduce the behavior: hook an external display

Screenshots If applicable, add screenshots to help explain your problem.

Additional context reverting binary modules to 5.4.191.g20220604 solves the problem. Can't compile these modules anymore. port tree 83f79ba0e0 (15 Nov). drm-510-kmod + gpu-firmware-kmod where compiled using 'make clean reinstall' Filed also https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267878
