Bug description:
In Lucid there isn't a dependency for myth-backend on kernel modules being loaded.  The result is that it can run before the kernel module for the hardware is finished loading.  The error looks like this in /var/log/myth/mythbackend.log

My current hack, which fixes the problem but is totally the wrong thing to do, is to add the following line to /etc/init/mythtv-backend.conf

/bin/sleep 60

Instead a proper dependency needs to be added in there, I just don't know enough about upstart to know how to do it.
