Package: linux-image-4.9.0-4-amd64
Version: 4.9.51-1

Running Samba in one docker container and mounting/umounting a SMB share of it
in a second docker container causes a kernel Oops.
The machine did not crash with linux-image-4.9.0-4-amd64=4.9.51-1.

The bug can be reproduced by https://github.com/fho/docker-samba-loop.

I was also able to reproduce a kernel Oops with the docker-samba-loop scripts
in multiple Ubuntu kernels (incl. machine crashes).
The trace looks different on linux-image-4.9.0-4-amd64. It might be a
different issue.
Ubuntu bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1729637
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1711407 might be related,
it's about the "unregister_netdevice: waiting for lo to become free."
messages.

The kernel log is attached.
