[lxc-users] lxc-start-ephemeral triggers kernel oops

Serge, thanks for looking into this.

Container creation
------------------------
lxc-create -t download -n trusty -B btrfs -- -d ubuntu -r trusty -a amd64
lxc-start -n trusty
lxc-attach -n trusty -- apt-get --no-install-recommends install x11-common
lxc-stop -n trusty

If the kernel oops can't be reproduced then it must be due to some
peculiarity of my
setup and is not worth chasing down.
