I'm using btrfs on two devices here, /usr on sda3 and /home on sdb (dm-crypt device on the whole disk). With btrfs-master the whole system hangs when accessing /home. The system hangs when I'm logging in into my account with KDE and is easily reproducible with dbench. On /usr the hangs appeared also but not as often as on the /home-device. I've tested on a third device with new created btrfs on top of dm-crypt, but wasn't able to reproduce the hangs. The filesystems are created without metadata-mirroring (-m single). I've bisected this to:
