This looks like ir-keytable could not match up your /etc/rc_maps.conf with
your rc device. Please can you provide:

1) output of "ir-keytable" no (arguments)
2) output of "cat /etc/rc_maps.conf"
3) output of "ir-keytable --version"

This is a warning message about the driver and should not affect
functionality,

What distribtion are you using and what version?
