You have been subscribed to a public bug:

When destroying a veth interface when both members of the veth pair are
up, a kernel bug is triggered.

How to reproduce:

ip link add type veth
ip link set veth0 up
ip link set veth1 up
ip link del veth0

I've uploaded the kernel log to
https://gist.github.com/jpetazzo/6190928.

In some cases, it completely locks up the machine. For instance, when a
LXC ocntainer is stopped, the bug happens, but the machine is then
frozen (no console, no reply to ping). I've uploaded the corresponding
kernel log to https://gist.github.com/jpetazzo/6190908.
