This is most probably caused by the fact that I forgot to add the
'option CD9660' to the kernel config files. I fixed this about a week
ago. So you can try adding the above line to config/FALCON and rebuild
the kernel or be patient and wait about a week. Because of the oncoming
release I will upload 2 intermediate releases.

Before speculating on the above, better check the option first ;-)
