  <pre wrap="">Hello!

We"ve got two different systems running with XFS, one of them is
publishing shares via NFS, the other via Samba. We've recently
encountered filesystem issues on both servers, and received the
following call traces. They look very much alike.

Are these something you are familiar with? We'd like to at least
establish that the problem really is with XFS... We don't really have
the possibility to update the kernels (2.6.27.10) on those machines, but
we can possibly apply patches etc. These systems are usually under a
fairly high load and host a large number of files.
