[Bug 1273386] Re: Neutron namespace metadata proxy triggers kernel crash on Ubuntu 12.04/3.2 kernel
AFAICT this is worked around in master by switching to config drive but
stable/havana devstack is missing support for that, so I've proposed

Title:
Neutron namespace metadata proxy triggers kernel crash on Ubuntu
12.04/3.2 kernel
Status in devstack - openstack dev environments:
In Progress
Status in OpenStack Neutron (virtual network service):
Triaged
Status in OpenStack Compute (Nova):
New
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
In the past 9 days we have been seeing very frequent occurences of
this kernel crash: http://paste.openstack.org/show/61869/
Even if the particular crash pasted here is triggered by dnsmasq, in
almost all cases the crash is actually triggered by the neutron metada
proxy.
This also affects nova badly since this issue, which appears namespace
related, results in a hang while mounting the ndb device for key
injection.

We have seen about 398 hits since the bug started to manifest.
Decreased hit rate in the past few days is due to less neutron patches being pushed.
