Is this related to your 5k snapshot drive and your attempt to go back 
kernel revs from 3.17.0 etc?

I see that you are using 3.17.1 kernel. Are you also up to the 3.17 
version of the btrfs tools?

You may be in deep error land from the long use of 3.10... that said, 
the --init-csum-tree or --init-extent-tree options may be your friend 
here. The backtrace shows you are in "open_ctree" so the former is more 
likely the better bet.

Do make _sure_ you are using a fairly recent (3.14.x at least?) version 
of btrfs tools. You might want to download and compile the latest (3.17) 
of the tools for this task even if you don't feel comfortable installing 
them (without an rpm etc).
