Comment 31 for bug 1273386

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.
