Yes.  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,
