kernel 6.4.0-150600.4.10  works as expected (last working installed kernel)
kernel 6.4.0-150600.9 is installed, but not kernel-default-extra, so no
nouveau.ko available
kernel 6.4.0-150600.12.1 oldest installed causing black screen and
non-responsive keyboard @KMS start
kernel 6.4.0-150600.23.17.1 newest installed (also bad)
