>Description:
I'm having trouble getting a 2114x-based Ethernet card (using the `dc' driver)
working on an i386.  Specifically, the card won't negotiate a link with any
Ethernet device I've tried.  Based on experimentation, it seems like the dc 
or phy drivers would be likely suspects.

Other than the chipset I know nothing about this card's origin or identity,
it doesn't have much in the way of useful markings.

Symptoms and possibly useful datapoints:

 - When the system is powered on, but *before* the kernel begins probing
   and initializing devices, the card displays proper link/speed LED's when
   connected to an active Ethernet (works as expected)

 - *After* the kernel has begun to initialize, link/speed LED's go dark, 
   even when connected to a known working peer using a known good cable 
   (tested with both a simple 10baseT hub and another Ethernet card with 
   crossover cable)

 - Output of ifconfig after boot also shows "no carrier" on the affected
   interface, agreeing with LED's

 - The same card works fine under Solaris 2.8 and FreeBSD 4.x, testing with
   similar conditions

 - The behavior persists regardless of slot placement (and receiving
   different IRQ's as a result)

 - For what it's worth, the other dc interface (different type of card from
   the non-working one) in this system works fine

A complete dmesg follows (note that dc1 is the problematic interface):
