I was surprised that the new source drm-66-kmod file built with the new kernel sources works fine with the month-old kernel. I had not touched world when booting the old kernel. It booted normally, though with several ugly looking errors which I= do not believe were related, but tied to starting IPv6 and Bluetooth. I'm gues= sing BZ has updated things in this area. Just now I rebuilt drm-612-kmod reinstalled it and rebooted. I It booted normally, though with several ugly looking errors which I do not believe we= re related, but tied to starting IPv6 and Bluetooth. I'm guessing BZ has updat= ed things in this area.t booted fine and Mate came up fine. (IPv6 also is working.)
