is it possible that your backend is starting before the kernel has
finished loading the modules for your tuner cards? It then can't see
them and things wil break. The kludgy trick is to set a few seconds
delay in the backend startup script. sleep 10 pauses for 10 seconds.
the other alternative theory is that the cards get swapped on startup.
sometimes modules get loaded in a different order and what was
/dev/dvb/adapter0/frontend0 on one boot will become
/dev/dvb/adapter1/frontend0 next time. You need to look at udev rules
to keep them consistent.
