So far no lockup with 3.16.0-rc6-tp520-fixcompwrite+ But BTRFS still not used up all space for laying out trees after balance: Label: 'home' uuid: […] Total devices 2 FS bytes used 126.70GiB devid 1 size 160.00GiB used 156.00GiB path /dev/dm-0 devid 2 size 160.00GiB used 156.00GiB path /dev/mapper/sata-home May be a good sign nonetheless, thus mentioned.
