Kernel with OCFS2 1.1.8?

The OCFS2 version in SP3 is 1.1.7. We have a severe problem with cluster nodes becoming unresponsive. After one node becomes unresponsive, the other is fenced by OCFS2 => cluster down. A suspect (among others) is OCFS2. Can we have a kernel with 1.1.8? It says it fixed some DLM mastery problems, whatever that is.
