re: Karl-Philipp's attached log, I had pretty much identical messages as well, just no crash like he did.
So now I'm suspicious this corruption was instigated by btrfs-progs 3.12's --init-csum-tree on a new btrfs volume. After updating to btrfs-progs 3.18.2, it showed many similar complaints as KP's log, but did not fix the csum tree using --repair --init-csum-tree. I then tried --repair by itself which appeared to fix the backref/extents problems. Then --repair --init-csum-tree did rebuild csum tree. As for the crash, I would say to try the Fedora btrfs-progs 3.18.2 package on this CentOS 7 system, maybe the crash is a bad compile.
