I can successfully boot into Ubuntu 11.10 (3.0.0-14-generic-pae) with a btrfs root filesystem and an ext2 /boot partition. But when I installed the latest vanilla (3.3.0-rc1+) and booted into it, the first time the system froze. Next time onwards, I get the following error every time: [ 0.427443] [drm:i915_init] *ERROR* drm/i915 cannot work without intel_agp module! mount: mounting udev on /dev failed: No such device W: devtmpfs not available, falling back to tmpfs for /dev mount: mounting /dev/disk/by-uuid/f43fdd7a-8ad7-4e96-ab1c-14ba82a4324d on /root failed: No such device mount: mounting /dev on /root/dev failed: No such file or directory mount: mounting /sys on /root/sys failed: No such file or directory mount: mounting /proc on /root/proc failed: No such file or directory Target filesystem doesn't have requested /sbin/init.
