Bug 950279

Description of problem:
Not entirely sure what caused this. Installed fresh Fedora 18, did all updates.
Noticed small/quick lockups/slowness after upgrading to the 3.8.5 kernel.
only noticing this issue with AMD cpu (Phenom x6 1055T) 20GB RAM (all same modules), ASUS M5A97 (970 chipset)
other then the quick lockups/slowness no other issues.

Hope this helps in some small way.
Keep up your awesome work guys!
