Hi! Thank you Hugo for your answers, but i have an update. "It's dead Jim." When i tried to mount subvolid=0 to a temporary folder i got a kernel segfault and a BUG line in btrfs kernel code somewhere (reproducable), after a reboot all volumes are broken, can't be mounted anymore... btrfsfsck gave me inode errors on subvol 256 (my home). mount does nothing but sleep/hang... Now i am trying to restore my system and home from a backup to a new harddrive, without btrfs at the moment... I think my question 6 is now answered: it's completely broken.
