If yes, some options you coud try:
- try "btrfsck -s1 /dev/sda1" (or whatever your /home block device is) to try alternate superblock. If it finish without errors, you might be able to use btrfs-select-super
- try btrfs-zero-log

btrfs-select-super and btrfs-zero-log isn't compiled by default, so you need to grab the sources and compile them with "make btrfs-select-super" and "make btrfs-zero-log"

Nothing like this in my dmesg and the command doesn't work. It return "Could not check mount status: Unknow error" I've upgrade btrfs-progs from git
