Have you connected a fw device to the > firewire card? I've been able to run a few more tests, even though I've not done abused it in every way I have in my mind yet... The evidence I currently have is: - if I load the modules at loader time everything is fine, with or without a device attached - if I load the modules later on, the kldload doesn't return and the system stops responding; I can still enter DDB. The only way to recover from that is to eject the card; at that point, the system is usable BUT as soon as there is network activity, the system freezes hard (can't get to DDB). IMHO this is 100% an interrupt problem. Does this ring a bell with one of you, or should I provide more info? Bye, Andrea -- The dark ages were caused by the Y1K problem.
