The usual cause of this is updating the kernel w/o updating modules. Or
you did an installkernel w/o a reboot. The cd9660 module only depends
n the kernel version because all modules depend on that to guard against
such foot shooting. Chances are good a simple reboot would have fixed
this. There's some anti-footshooting code to load it from kernel.old, but
I've not tested that in years, so maybe it's no longer working (or you did
multiple installkernels.
