------- Comment From spieth.com 2011-03-23 11:41 EDT------- According to: https://bugzilla.linux.ibm.com/show_bug.cgi?id=66345#c65 A patch may be available. Please consider as an exception.

Please consider as an exception. Which is Red Hat bug 613812 and likely comment 43. I can't seem to view that bug under the bugproxy.com id to tell you for sure.
Since RHEL 6.1 External Beta has begun, and this bug remains unresolved, it has been rejected as it is not proposed as exception or blocker. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux.
Hello IBM, This is to late for an exception. This will be requested for RHEL 6.2. Thank You Joe Kachuck
This should be fixed in RHEL 6.1 as of kernel build -128, please see the BZ that this one has been marked a duplicate of. *** This bug has been marked as a duplicate of bug 685161 ***
