The ones I have seen (and are both repeatable) are when powering off the modem and powering it on causes the system to hang solid. Also if an incoming call is received on the telephone, the system hangs ( I assume that this is when the modem sends 'RING' and asserts the RI hardware signal.) The serial port is used only for outgoing connections and there is NO getty process listening on it. I would suspect a hardware problem, except that I have never seen this before and on reverting to 2.4.0-test12 these actions do not cause any problems. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
