I ordered a new Dell SC440 , with the pentium D and the infamous broadcom bcm5754 (or is it 5787?) . I started off with OpenBSD 4.0 release, then noticed a kernel panic on reboot. This was a consistent repeatable problem, and after googling I noticed other people having the same problem and some patches specific to this card in current. I am now on current (as of January 31) and and I receive no kernel panics on reboot. If I insert a live cable into the card, it ifconfig bge0 will show that it detects a connection and sets the appropriate media type. However, this card will not actually work. I cannot receive an ip address by calling dhclient bge0 , nor can I manually assign it an IP address and ping it from another machine. I have tried manually setting media options, all manners of things and no dice. I installed a linksys lne100tx card using the dc driver just to test and it works as expected. Attached is copy of dmesg output.
I have a Dell SC420 that had problems routing interrupts for multiport NICs. In 3.9 the system would stop responding when bringing the second em(4) interface up. In 4.0-current, no lockups but the interface was unusable (like your situation above). However, enabling acpi in -current fixes this. From my experience, I'm guessing that these lower end Dell machines have broken old pci intr routing but working acpi.
It looks like -current fixed your panics, so try boot -c and enable acpi. I'm interrested in knowing if this fixes your problem. But it might not be applicable to you since I couldn't see your dmesg.
