Stefan, what's the most important thing we could do to help you help us? I see a few threads of inquiry in the comments that trailed off:
- abstracting Salvatore's script for high thrash rates on VM creation/destruction and network namespace creation, to try reproducing the issue without running openstack - ext4 vs ext3 - capturing crashdumps from a devstack gate run (or simulated gate run on a local machine) - determining whether the failure is a regression from a previous version of the kernel (seems not) - determining whether the failure occurs on 3.11 kernel in addition to 3.2 kernel (seems it does) What looks most promising? This is a critical issue, and still producing intermittent failures, so it's worth a prod or two on the OpenStack side to get things rolling again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1273386 Title: Neutron namespace metadata proxy triggers kernel crash on Ubuntu 12.04/3.2 kernel To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1273386/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
