Public bug reported: 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.
