This is due to a mismatch between the running kernel image and the
module you try to load.
$ cat /proc/version
$ sbin/modinfo -F vermagic vfat

Update the boot loader and reboot the system after a kernel upgrade. If
it does not solve the problem, check the active boot loader loads the
correct kernel image. (I remember a case where the actual boot process
did not use files in /boot but from another, not updated, location)
