Comment 2 Beth Uptagrafft 2015-04-08 21:06:30 UTC

This issue has not been updated in a while and is using an older, unsupported kernel. This BZ is being closed WONTFIX.  If you believe  this is still an issue on our most recent MRG-2.5 3.10 Realtime kernel, please file a new issue for further investigation.
