Nasty regression bug and it must not be consistent as it only happens on
one of our systems, knock on wood, so far. Yes, the last thing we had
done was turn off an selinux bool that was a work around until an update
came out to fix it yesterday. Unlike the bug report which indicates you
can to a sync && reboot, nothting but the power switch gets this system
out of the issue. We hope there is a fix for this soon.
