At the weekend; I updated my Linux Box. After the update, I rebooted my 
box as usually. When I tried to log in, X or KDM was frozen. I had no 
choice but hard reset. After the hard reset; when powered on again, I 
hit the below btrfs bug :

So, this bug ate all of my root file system :-\ When mounting or running 
btrfsck, the same error occurs. I tried with 2.6.37-38 and 3.0-rc5 
kernels and the result is all the same. It looks like a long time bug 
that sits in btrfs code. I hope the above error message can help. 
Because, I had to re-format my disk :-\
