Modprobe Can't Locate Module, XXX, and Similar Messages

These types of messages mostly occur at boot time or shutdown. If
modprobe, insmod, or rmmod complain about not being able to find a
module, add the following to the /etc/modules.conf or
/etc/modutils/aliases file, whichever is present on your system.

$ alias off

And use the name of the module that appears in the error message.
