The situation was that I was working in my /space directoy. mount says the following about the /space partition /dev/sda3 on /space type btrfs (rw) I also (previously) had a usb stick mounted at /dev/sdf also formatted as btrfs. This was however removed prior to the crash. I am not sure if the machine synced before I removed - but there is a string possibility that it did, because the usb stick carried a root filesystem for a dockstar, which is currently running fine with exactly that root filesystem.
