The fix is in the 3.8 kernel.

I'd also advise setting up proper node definitions in corosync.conf;
it avoids the invalid nodeid issue and makes everything cleaner.
Here's what I use:

totem {
        version: 2
        secauth: off
        cluster_name: foo
}

nodelist {
        node {
                ring0_addr: 1.1.1.1
                nodeid: 1
        }
        node {
                ring0_addr: 2.2.2.2
                nodeid: 2
        }
}

quorum {
        provider: corosync_votequorum
        two_node: 1
}                                                                               

logging {
        to_syslog: yes
}
