Description:

My root partition is using btrfs, and after upgrading btrfs-progs to 4.2.3 the boot stops on "scanning for btrfs file systems".
When booting on a live usb, the partitions are mountable and usable with both 4.2.2 and 4.2.3.

Downgrading to btrfs-progs-4.2.2 fixed the issue.


Steps to reproduce:
Install Archlinux on a btrfs partition.
Maybe it is related with the fact that I am using a SSD.

/etc/fstab:
```
/dev/sdb1 / btrfs rw,relatime,ssd,space_cache 0 0
/dev/sdb2 /home btrfs rw,relatime,ssd,space_cache 0 0
```
This task depends upon

Works fine for me.
