Ok well that's not good, I'm not sure how you got a 156 gigabyte block group,
but thats why that warning is going off.  Can you pull btrfs-image down from
here

git://github.com/josefbacik/btrfs-progs.git

and build that and then run

./btrfs-image -c 9 -t 4 /dev/whatever somefile.img

and upload the image somewhere so I can take a look at it.  Thanks,

Josef
