This kind of crashes happens me very often when I delete a large
number (+200) of snapshots at once.
There is a very high IO for a while, and after that, the system
freezed at intervals. I had to reboot the system to get it responsive
again.
Versions used:
kernel-3.13.6-200.fc20.x86_64
btrfs-progs-3.12-1.fc20.x86_64

Not sure if this has been fixed...
Can you try btrfs-next or compile the kernel with CONFIG_DEBUG_SPINLOCK=y?
thanks,
