My system is trusty, but I assume later versions and even upstream are affected. Steps to reproduce: - run an amd64 kernel via multi-arch on an i386 system - Try to "btrfs send" or "btrfs receive" a subvolume Result: $ sudo btrfs send /mnt/LTS/snapshots/home-daily-2017-03-16/ -f /tmp/home-daily-2017-03-16.btrfs At subvol /mnt/LTS/snapshots/home-daily-2017-03-16/ ERROR: send ioctl failed with -25: Inappropriate ioctl for device This occurs with 3.13.0-96-generic as well as 3.13.0-114-generic (which fixes bug 1619918).
