I've tried, and I'm not able to reproduce what you're seeing -- which seems to be triggered by a udev rule that calls /lib/udev/v4l_id. I see that run here too, but no hang. I'm on a different distro though, and defaulting to NTSC instead of PAL, which could be somehow relevant here. If you disable the udev rule (/lib/udev/rules.d/60-persisten-v4l.rules if I'm remembering correctly), do things come up okay? It could well be that for some reason, in your setup, that rule is running while the card isn't actually all the way initialized. Assuming that helps, IR *should* be working, though you'll need the two patches I posted yesterday to make it behave better. With those, the 1150 is handling rc5 and rc6 decode both in-kernel and via lirc userspace just fine now. -- Jarod Wilson jarod@xxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
