Description

I've noticed when using v0.25pre-3329-gbececaa-dirty that sometimes (maybe 75%) after rebooting my HTPC mythbackend cannot initialize DVB cards correctly until I restart mythbackend. Attached logs show "Opening DVB frontend device failed. eno: Bad address (14)" for both of my DVB cards. My setup used to work ok with approx month old trunk build until last weekend when I updated the system (same OS Fedora 13 with 2.6.34-9 kernel used with both builds).

However DVB cards are initialized correctly in the bootup because I can watch DVB channel using mplayer even though mythtv gives this error.

This isn't a mythbackend problem, it's a "your init script is starting the backend before it has initialized the DVB devices" problem. The devices *are* initialized at boot properly, but by the time you get to being able to use mplayer, your distro has long since started Mythbackend too early, a condition from which myth is not designed to recover.

Please start on the mythtv-users mailing list to get assistance in changing the order in which your distro starts services.
