Comment 9 for bug 549428

So I hit this today, it looks like the same bug, but no apparmor update.

My system has permanent IO load, and all apps hit the disk hard whenever they do something.

sudo cat /sys/kernel/security/apparmor/profiles
/usr/sbin/tcpdump (enforce)
/usr/sbin/libvirtd (enforce)
/usr/sbin/cupsd (enforce)
/usr/lib/cups/backend/cups-pdf (enforce)
/usr/lib/libvirt/virt-aa-helper (enforce)
/usr/bin/evince-thumbnailer (enforce)
/usr/bin/evince-previewer (enforce)
/usr/bin/evince (enforce)
/usr/lib/connman/scripts/dhclient-script (enforce)
/usr/lib/NetworkManager/nm-dhcp-client.action (enforce)
/sbin/dhclient3 (enforce)
/usr/share/gdm/guest-session/Xsession (enforce)

aa-status reports similar output

I wonder whether this is really apport; perhaps it's ecryptfs.

I did a sudo perf top, and got:
             3415.00 - 19.8% : read_hpet
             1398.00 - 8.1% : find_vma
             1151.00 - 6.7% : drm_clflush_pages [drm]

              252.00 - 1.5% : schedule
              233.00 - 1.3% : copy_user_generic_string
              201.00 - 1.2% : kref_put
              199.00 - 1.2% : unix_poll
              182.00 - 1.1% : _spin_unlock_irqrestore
              177.00 - 1.0% : clear_page_c
              165.00 - 1.0% : kref_get

or is this drm? that sounds really heavy
