But there's a possibility to know in some way (via software) how irq lines are connected together? (maybe through /proc/interrupts) If there's such a possibility, i think i can try to shuffle irq in way that minimize conflicts. Or maybe not, because interrupts are always the same... Another question, but bttv chip are on the same card and with Thanks. -- -gaspa- ----------------------------------------------- --------- http://launchpad.net/~gaspa --------- ------ HomePage: iogaspa.altervista.org ------- -Il lunedi'dell'arrampicatore: www.lunedi.org - -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
