I know this isn't necessarily FreeBSD related, but I'm running out of options and figure it wouldn't hurt to get some sage advice from those in the know in here. I've recently upgraded one of my servers from a P233MMX to a dual PPro200, running a Tyan S1662 TitanAT SMP board. I have two 3Com cards in there, a 3C905-TX and a 3C905B-TX. They both seem to be sitting on IRQ 11, and no matter what I do in the BIOS PnP/PCI settings, they seems to be stuck there. I tried setting IRQ 11 to be legacy/ISA assigned, but that only pushed them both to IRQ 15 (I have my IDE controllers disabled as this is a all SCSI system). Does anyone have any ideas on how to move them to separate IRQ's? I even tried the 3Com diag util (disk 2), but it doesn't allow me to change IRQ's. On a separate, but more FreeBSD-related issue. After installing FreeBSD-STABLE (cvsup'ing and world), SMP works great, but networking is hellishly slow. Can I assume this is a symptom of the IRQ conflict? If it's any help, GENERIC doesn't seem to have this problem. But then, GENERIC doesn't have SMP in it. I'll see about building a GENERIC kernel with SMP and see if I get the same network issues as well (2000+ms ping times out to the internet!). Thanks in advance.
