I thought about termination before writing, but the cabling is the same cabling that it had when it was in the 2.2.1-STABLE box, I thought it was terminated properly (but does the 1542CP do auto-termination on its internal connector if there's nothing connected there? -- can't find TFM), I've been over it just in case I wiggled a connector loose during the box swap, and I've replaced a 6' cable with a 3' just in case. No joy doing that. But this morning I changed the card's idea of its IRQ to 9 and it all works with no "create_intr" complaint. I'm guessing that IRQ 11 was falling foul of (and being changed to -1 by) the "#ifdef APIC_IO" code just before the call to register_intr() in config_isadev_c(), but as I'm not sure what is going on in that code I think I'm just going to rejoice and do a backup now that I can get to my tape drive. > The driver doesn't use the hardware status bits that can tell if the > cable configuration is illegal, nor does it tell you if the > termination is bad.

OK, here's a couple of additional data points: plug and play is disabled on this card, and this is all now plugged into a Tyan S1832DL "Tiger 100" motherboard with two CPUs. -Frank McConnell To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
