I have since rebooted to 3.6.9-2.fc17.x86_64, 3.6.10-2.fc17.x86_64 as well as 3.6.9-4.fc18.x86_64, 3.6.10-5.fc18.x86_64 and 3.6.11-3.fc18.x86_64; and all have the same problem. 3.6.9-2.fc17.x86_64 was the last kernel which I ran for over two weeks and had suspended a few times according to my /var/log/messages*.
