I reran the command on a 1GB loop device (with the same result), and here is
its gzipped image: http://media.romanrm.ru/tmp/btrfs-made-on-arm.img.gz (1M=

This can't be opened by btrfsck with the same error message, and on amd64 t=
oo.

btrfsck: volumes.c:1575: btrfs_read_chunk_tree: Assertion `!(ret)' failed.

So the problem is clearly with mkfs on ARM, creating an invalid FS.

With respect,
