Don't know why but I have seen several of my rawhide machines doing this, but I did not bother to check what was going on and just pressed power button so that they could shutdown all the way.

I question SELinux as the root cause, because:
1. The problem has existed for a while with no AVC denial.
2. I ran in permissive mode, anyway, and still saw the bug.
3. The bug only happens sometimes, but SELinux would be all the time.

In other words, I think SELinux is a new bug that should be fixed, and I 
think we still need to keep looking.  I haven't done much testing in the 
last week, half because of the freeze making nothing new available to 
test.  Now I've got a copy of the Preview DVD, so I'll crank it up again 
today or tomorrow and see what I see.  I heartily encourage everyone 
else to do the same.
