Well, none of these are normal avcs that you would see if selinux was
denying access to something.
A classical avc that makes trouble looks like this:
Sep 2 05:03:13 hostname kernel: audit(1188705793.190:416): avc: denied
{ search } for pid=12965 comm="wpa_supplicant" name="netdev:wlan0"
dev=debugfs ino=2841020 scontext=user_u:system_r:NetworkManager_t:s0
tcontext=system_u:object_r:debugfs_t:s0 tclass=dir
The avcs are pretty verbose about who what where and when.
[root@k5di ~]# grep avc /var/log/messages
Oct 11 02:31:08 k5di dbus: Can't send to audit system: USER_AVC avc:
received policyload notice (seqno=2) : exe="/bin/dbus-daemon"
(sauid=500, hostname=?, addr=?, terminal=?)
Hum seems to be some meta information about loading policies, not in
itself an error, although I dunno what "Can't send to audit system" means.
Oct 11 02:52:39 k5di setroubleshoot: [avc.ERROR] Plugin Exception

Seems to be setroubleshoot crashing, again not directly itself an error
caused by selinux.
Not much the wiser except that there don't appear to be any actual
selinux avcs in there and something is unhappy somehwere.

Come on Andy, there are a whole lot of AVC things and they explain why
the computer came up so slow. SELinux was trying to get some things done
and they were not succeeding so it slowed everything to a crawl.
What is there are reports of error, and I got them from
/var/log/messages/ and explains to me how SELinux slowed down my computer.
