Title:
XFS instability on armhf under load

Status in linux package in Ubuntu:
Expired

Bug description:
We've observed issues with XFS on ARM hardware on both 12.04 and
12.10. Details from ubuntu-bug are attached from a 12.10 installation.
The specific load in this case is setting up and running a single node
install of Swift and then exercising it with swift-bench for a
prolonged period. After a few hours you get the following:
