>Description:
While others with the exact same card have reported no problems, any
attempt to ifconfig dc0 results in a stream of watchdog timeout messages
to the console.  (Additionally, no traffic can be sent)

dmesg lines look like:

dc0: <82c169 PNIC 10/100BaseTX> port 0xa400-0xa4ff mem 0xdd800000-0xdd8000ff irq 10 at device 13.0 on pci0
dc0: Ethernet address: 00:a0:cc:d3:54:45
miibus0: <MII bus> on dc0
ukphy0: <Generic IEEE 802.3u media interface> on miibus0
ukphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

I have two other cards in this box: an intel eepro (fxp0) and a
3c905 (xl0).

The ifconfig looks like this when it's up:

dc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 196.168.1.2 netmask 0xffffff00 broadcast 196.168.1.255
        ether 00:a0:cc:d3:54:45 
        media: autoselect (10baseT/UTP) status: active
        supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP none

>How-To-Repeat:
(My guess):
Make a system out of:
K6-2/400
Asus P5A motherboard
put in it: Matrox Millenium II (PCI), Intel EtherExpress Pro 10/100,
3Com 3c905 (no A, B, or C), NetGear FA310TX, 1IDE drive, 1IDE cdrom.
Build a kernel with dc0, xl0, miibus, and fxp0 built-in, as well as
IPFIREWALL, IPFILTER (trying them both out), BRIDGE, NETGRAPH, 
IPSTEALTH, and other fairly standard stuff.  Try to use dc0.  This
is with stable as of the date and time given in the Environment
