If the latter, > how do you know the modem caused it? No, not ejecting the card; but accessing the network over the modem. I don't know 100%; but I have never had a lockup when the modem was not in the machine and it generally seems to be associated with some kind of modem activity. Other that this, they system is rock solid. > The modem won't work at all reliably in PIO mode. The interrupt load is > difficult enough to keep up with in non-polled mode.

Ok; thought it might be an interesting experiment. > Or, are you talking about the PCIC controller (which generates > insertion/removal event)? Hmm, might be a worth while experiment; at least would give me another IRQ to try. Is it enabled by setting the PCIC IRQ to 0? Any other ideas on how to isolate this appreciated. many thanks, Mark To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
