I'm not sure how I triggered this. I've been moving around between networks and suspending/resuming all day.
Earlier in this boot I successfully used a container (start, networking and stop). I came to start the same one later and noticed that it didn't come up. Trying to attach to the console with lxc-console informed me that it wasn't running. I then saw suspicious content in dmesg:

SRU Justification:
Impact:
When creating new network namespace dmesg can show the following
unregister_netdevice: waiting for lo to become free. Usage count = 1
Fix:
Stefan Bader's SAUCE patch has fixed this for Quantal:
UBUNTU: SAUCE: net/ipv4: Always flush route cache on unregister batch call
Testcase:
The sourcecode found here:
https://lists.debian.org/debian-kernel/2012/05/msg00494.html
can be compiled and run as follows:
sudo ./reproducer
#ctrl+c
sudo ./reproducer
#wait for a while
dmesg | grep unregister
--
I'm not sure how I triggered this. I've been moving around between networks and suspending/resuming all day.
Earlier in this boot I successfully used a container (start, networking and stop). I came to start the same one later and noticed that it didn't come up. Trying to attach to the console with lxc-console informed me that it wasn't running. I then saw suspicious content in dmesg:
[25800.412234] INFO: task lxc-start:25817 blocked for more than 120 seconds.
