I've had this happen to me too. My theory has been that either it has
nothing to do with Fedora at all and it is a BIOS problem or that the
grub device.map file gets reversed somehow. 

In either case, you would have to have 2 disks so
perhaps we can determine if anyone who has seen this problem only has
one disk which would dispel my theory.
