2.6.38.8-32.fc15 is fairly old at this point. Are you seeing this issue with 2.6.43/3.3?
Fedora 15 has reached it's end of life as of June 26, 2012. As a result, we will not be fixing any remaining bugs found in Fedora 15. In the event that you have upgraded to a newer release and the bug you reported is still present, please reopen the bug and set the version field to the newest release you have encountered the issue with. Before doing so, please ensure you are testing the latest kernel update in that release and attach any new and relevant information you may have gathered. Thank you for taking the time to file a report. We hope newer versions of Fedora suit your needs.
