The differences in btrfs between the two are very small, and even I(*) wouldn't call 3.8.0 "very old" quite yet, given that 3.9 was only released yesterday. From memory, there's one btrfs patch in the 3.8 stable series. Your problem is "just" a warning, and appears to be something to do with running out of space, or having too many CRCs... I don't really know the free space cache code at all well, so I'm mostly guessing here, from looking at the WARN_ON in __btrfs_write_out_cache. Hugo.
