It's possible you're getting a configuration conflict between the
network adapters and the switch/hub.  If one is in full-duplex mode and
the other is in half-duplex, you'd get very poor traffic flow and lots
of errors reported on the device.

You might try using mii-tool and/or mii-diag to investigate further.
Depending on the revision of the adapters (are they DE4xx or DE5xx?)
they may also have broken auto-negotiation, in which case you'll want to
manually set 10baseT.

[gentoo-alpha] Gigabit cards

[Jacob Joseph]

Hi.  I'm planning to upgrade a few alpha machines to gigabit networking(along 
with the rest of our computational machines) and wanted to get any stories of 
success/failure with respect to specific cards?  I've had good luck with 
intel cards and the e1000 driver on x86 machines?  What cards do you use?

Thanks
-Jacob

I have a personal bias toward the Broadcom 5703-based adapters, but
that's because I wrote the Tru64 driver for them.  ;-)  I've heard that
the Linux drivers for those adapters aren't very good, but that's
definitely second-hand knowledge.  

I haven't personally used Gigabit under Linux so let us know what you
choose and how things work!
