Seconded.

Also, if you're not aware of the btrfs wiki yet, you probably want to 
read up on btrfs there.  It stresses btrfs' development nature and the 
importance of running a current kernel for btrfs testing in several 
places, so the fact that you're not doing so indicates that you probably 
hadn't read the wiki, and are thus likely missing out on other 
potentially very useful information, as well.
