 If you can run 'btrfs check' on it (without repair) using btrfs-progs
 4.0, and 3.19.1, and report the results of each, that would be really
 useful.

Here we go.

Best,

 Hello!

 I also hit the Btrfs read-only after btrfs-convert bug when converting my
 Ext4 root filesystem with btrfs-convert. I used the btrfs tools v4.0 and
 Linux kernel 4.1.1.

 As a workaround I mounted the converted Btrfs read-only and copied it to a
 new Btrfs created by mkfs.btrfs (from the btrfs tools v4.0). Debian 8
 system booted without problems, and the bug hasn't been seen (so far).

 Output of uname, btrfs, and the dmesg log is attached. Let me know if you
 need anything else. The old Btrfs is still on another disk, and I can
 extract information from it.

If you can run 'btrfs check' on it (without repair) using btrfs-progs
4.0, and 3.19.1, and report the results of each, that would be really
useful.
