I finally managed to create a reproducer for the XFS hang but the provided kernel does not solve the problem. It hangs within a few seconds, just like the original 2.6.38-8-server kernel. I also tried the following Ubuntu kernels but they both hang within a few minutes. Do run a little longer than 2.6.38-8 and -14 though. 3.0.0-17-server 3.2.0-23-lowlatency
Next I tried the upstream stable kernels but they also hang within an hour: 3.0.29 3.1.10 3.2.15 3.3.2 A typical stacktrace is attached. Once the task is hanging, the directory or partition becomes unusable and only an emergency sync clear things up again.
