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 guessing 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 were related, but tied to starting IPv6 and Bluetooth. I'm guessing BZ has updated things in this area.t booted fine and Mate came up fine. (IPv6 also is working.)
