The dmesg you attached is from an F14 kernel.

Linux version 2.6.35.13-91.fc14.x86_64 (mockbuild.fedoraproject.org)

I'm not sure why you're still using an F14 kernel on F16/F17 but there is nothing we can do with this.  If you can recreate the issue on the latest F17 kernel (3.4.4-5.fc17) please reopen.
