I see 3.5.0-19.30 has been released for Quantal but grepping through the
changelog and the entire source tree indicates that the patch has not
been applied to that kernel. Am I incorrect?

@Jean-Baptiste,
I think I've found the offending bug and upstream commit
3d861f661006606bf159fd6bd973e83dbf21d0f9 "net: fix secpath kmemleak"
fixes a reference counting issue that stops lo from becoming free.
I've build some test kernels, perhaps you could try the appropriate one
and let me know

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

and start a new one it gets into a lock contention.

Sounds like I'm in the same boat. Exact same symptoms as above,

reproduce i
** Description changed:
Reproduced with 3.5.0-17-generic #28-Ubuntu x86_64 on 2 different

TEST CASE:
On a fresh installation of Quantal with all updates applied run:
On the host
1. sudo lxc-create -n test01 -t ubuntu -- -a amd64 -r quantal

I did the following additional tests:
1) Download 1MB at 5kbps: PASS
