The kernel bug manifests when mounting of nbd devices is combined with ip namespace operations. Using openstack it can be reproduced only with the following configuration: - compute service must run on the same node as the dhcp-agent and/or the l3-agent - file injection should be turned on: libvi

Stefan, regarding comment #12 A few of us have noticed that recent changes in the testing framework are causing neutron network resources to not be deleted (I filed bug 1274410 this morning, but we have known about this for almost a week unfortunately). A side effect is that this leaves a rather

It looks like the OVS and DNS failures were due to nodes not properly built and these issues were resolved. However, experimental jobs seem to be revealing "Timed out waiting to get to ACTIVE" errors without any kernel crash dump. The error is still what appears to be a hang while mounting the n

We have now rolled the new kernel in the nodes used for the experimental jobs. This did not help anyway. In the logs the 'waiting for thing to become ACTIVE' failures are still present, but there is a different failure mode (no kernel crash). However, openvswitch is just not working [1] and the

Hi Stefan, I have a few more info. I am trying to run the tests which trigger the issue on two machines, one with 3.2.0-57 and the other with 3.2.0-58. So far, after 20 runs on each machine, the crash did not happen, so I can't yet confirm the regression. However, back in october we had another

I've run the related patch twice, and the kernel bug was hit even with SIGTERM rather than SIGKILL. I think this kind of confirms that "failure to become ACTIVE" error is related to issues while terminating metadata proxies and dnsmasq instances. -- You received this bug notification because you

More info. The crash actually happen when a process is killed. This has consistently happened in 10 failures I've analyzed. So the first conclusion is that this might be, after all, a red herring, and the kernel dump being merely a consequence of the abrupt killing of a process. I've pushed this

I have worked a bit more on this issue, and it seems that the crash happens when a process is executed in a namespace. So it's not the metadata proxy doing something that crashes the kernel, but is the act of launching the metadata proxy which causes the crash. -- You received this bug notificati
