Should be in the archive today or tomorrow. This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping I have been unable to reproduce this issue with recent versions of the Fedora 11 kernel. |
