Comment 2 RHEL Program Management 2012-05-03 05:23:34 UTC

Since RHEL 6.3 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.

Comment 5 Linda Wang 2016-08-25 14:59:19 UTC

This issue has been reported against RHEL6.1.
Since we have not encountered or able to
reproduce this issue with our latest kernels,
and due to lack of information, we plan to close this bz.
If you have encountered these issues again, please 
feel free to reopen the BZ.

many thanks!
