This bug is awaiting verification that the kernel for Quantal in -proposed solves the problem (3.5.0-20.31). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-quantal' to 'verification-done-quantal'. If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

I installed kernel 3.5.0-18.29-lp1065434 and did the following tests: - Ran the test case in the description - Copied bigger files (up to 1.4G) - Copied data from the host to the container and the container to the host - Copied data from a network host to the container and the container to a network host - Copied data over a wired and wireless link - Shutdown/restarted the container several times from the container with poweroff and from the host lxc-stop I couldn't reproduce the issue while it's reliably reproducible with the version of the kernel in 12.10. It sounds like the patched kernel resolves this issue.

[Bug 1065434] Re: unregister_netdevice: waiting for lo to become free. Usage count = 1 after LXC container shutdown
== SRU Justification == Copying a fairly large amount of data over the network inside a container and then exiting the container can trigger a missing decrement in the per cpu reference count on a network device. The result is the kernel error message: unregister_netdevice: waiting for lo to become free. Usage count = 1 ..and the next time lxc-start is started it just hangs. == Fix == The following upstream commit 3d861f661006606bf159fd6bd973e8 fixes this issue by releasing all possible references to linked objects. == Impact == Users copying large amounts of data over the network inside a container can trigger this bug and cannot exit the container and restart it. == Test Case == To trigger the bug: On the host: 1. sudo lxc-create -n test01 -t ubuntu -- -a amd64 -r quantal 2. sudo lxc-start -n test01 3. Login with ubuntu/ubuntu Inside the container: 4. Copy an amount of data from the network (scp from your local network or wget below) 4.1 sudo apt-get update sudo apt-get -y install wget 4.2 wget cdimage.ubuntu.com/daily-live/current/quantal-desktop-amd64.iso 5. Download more than 250MB and press CTRL+C 6. sudo poweroff On the host: After a few seconds one will see the kernel warning appear: unregister_netdevice: waiting for lo to become free. Usage count = 1 7. sudo lxc-start -n test01 ..and this will hang. With the fix, the error message will not occur and step 7 will not hang. One can run lxc-start and then exit the container multiple times without it hanging -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1065434 Title: unregister_netdevice: waiting for lo to become free.

it appears that if I wait a minute or so between destroying a LXC and creating the next one it seems to be okay ... so I'm guessing it takes longer for a portion of the networking to be shut down and if you try and start a new one it gets into a lock contention. # juju destroy-service test # sleep 60s # juju deploy --repository=examples local:precise/test seems to be enough to keep things working.I've done this about 5/6 times now without bad stuff. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1065434 Title: unregister_netdevice: waiting for lo to become free.

Hi, I do hit the exact same issue on my systems, its not ubuntu, but for what's it worth I did tested the vanilla 3.5 and 3.6.3 kernel and the bug is present there, maybe that can a bit help when you know that none of the ubuntu's kernel patches have anything to do with the issue. I can reproduce it on normal hardware and in KVM virtual machine with e1000 card. Whats is common between all my systems is that lxc uses VETH driver and connect to bridge.
