I just had this to pop up. SELinux is preventing /usr/bin/ABRT-dump-oops from open access on the file /var/log/messages. I have done a search on the net but not really sure if I should be concerned about this. I am running Fedora 15 lovelock on a Satellite lap top. I don't know if this matters but when I shutdown it seems to take very long time before doing so. The screen goes dim and stays there until it does shutdown. Also dual boot with win7.
