 my filesystem doesn't want to mount. running btrfsck produces

 I have compiled btrfsck from 
 git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs-unstable.git

 Is there anything i can do?

 With regards
 Libor

 (sorry for formating, i'm using webmail, because i don't have /home 
 partition now)
