I believe this is a regression in the ACPI layer. Can you attach the output of acpidump? Created attachment 594274 [details]
ACPI dump
Here goes.
OK, this does indeed look like the kernel.org bug I linked to. Your machine's ACPI lacks _DOS. I'll try to get a fix committed today. Please try this scratch build kernel when it completes: http://koji.fedoraproject.org/koji/taskinfo?taskID=4196863 I tested it several times, and it appears to work. Thanks! Thanks for testing. Fixed in Fedora git. kernel-3.4.4-5.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/kernel-3.4.4-5.fc17 kernel-3.4.4-4.fc16 has been submitted as an update for Fedora 16. https://admin.fedoraproject.org/updates/kernel-3.4.4-4.fc16 Package kernel-3.4.4-4.fc16: * should fix your issue, * was pushed to the Fedora 16 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing kernel-3.4.4-4.fc16' as soon as you are able to, then reboot. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2012-10319/kernel-3.4.4-4.fc16 then log in and leave karma (feedback). kernel-3.4.4-5.fc17 has been pushed to the Fedora 17 stable repository.
