I had actually forgotten that I had a separate ext4 boot partition. I've ran fsck on it as well as btrfsck on my mirrored root, and my raid10 array. All return fine. During boot, between some of the xfermode errors, I can see the message where it is looking for btrfs file systems, and then a repair console which says that the root filesystem can't be found which doesn't respond for some reason. I'll try to find another keyboard to see if it will make a difference. I did another install of of the old 3.6 kernel, and noticed that it threw an error about not being able to find the root filesystem at that point also. Any further diagnostic advice will be appreciated. Thanks, =-Jameson
