Could you try a newer kernel?

2.6.32 is expected to fail entirely because it did not support physical
NICs in containers.  I seem to recall some churn about how to handle
devices when a netns is destroyed.  At one point they were moved back
to the initial netns.

If the behavior you're seeing with 2.6.35-25-virtual is still happening
with 2.6.39, then lxc will need to work around that by moving the nic
back to the host netns before shutting down the container (or kernel
behavior fixed/changed).
