I don't really understand why ivtv modules causes those problems. (IIRC it was Sigmund, i think) > If more verbose messages are needed from othe modules please let me > know.

Without any any driver loaded for the ivtv hardware, do you still experience the same problems ? Is the ivtv hardware sharing interrupts with the Mantis ? My guess would be that the ivtv drivers grab a lot of IRQ time on the CPU leaving little shared IRQ time for other devices. Can you verify this ? _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
