The patch fix for this missed the 2.6.20 window.
The following link has all the relevant patches atop 2.6.20.

The kernel has changed much. 1.2 will not build against 2.6.20.
We have updated autogen to handle rhel5, but that's still 2.6.18.
What are you trying to achieve? Why not use the ocfs2 modules
shipped natively with fc6? If you want to run database, specify
filesystemio_options=odirect in init.ora.
Please file a bug in oss.oracle.com/bugzilla with the full strack trace.
The kernel BUG line looks wrong or at least incomplete. Is this the
full trace? If you have hit this on more than one occasion please do mention
that in the bugzilla. Maybe even upload the stack trace from those
instances t
#define ECONNRESET 104 /* Connection reset by peer */
#define EPIPE 32 /* Broken pipe */
Harmless. But do file a bug. oss.oracle.com/bugzilla. We should not be
printing the ERROR. It should be handled by the userspace.

ocfs2 init script is mounting devices listed in /etc/fstab.
Check the device names. If you are mounting by device name,
the name may have changed. If so, fix the device name and also
look up mount by label in the docs.

You may want all nodes to be on the same kernel version. 2.6.5-7.283.

This release provides the long awaited configurable network
