I did not have this error in Fedora 15 and I am seeing this error in Fedora 16. I installed Fedora 16 using the DVD ISO image with selecting the Fedora 16 and Fedora 16 Update repos. This same error occurs in 32-bit and 64-bit versions on two different laptops.
Loading Linux 3.1.0-7/fc16.x86_64

See attachment for pic of error message.
Fedora 16 seems to run fine, not sure what is causing this error or how to correct the error.
