Especially a lot of page locks which are controlled by the VM and not the filesystem. Can you try with commit 8aa7e847d834ed937a9ad37a0f2ad5b8584c1ab0 from 2.6.31-rc applied, or better directly 2.6.3-rc6? I would be surprised if this is something inside XFS, but running with CONFIG_XFS_DEBUG never hurts.
