I currently have the equivalent of 8 of these in my system (Compaq NC3131,
quad ethernet..)

Bus 2, device 4, function 0:
Ethernet controller: Intel Corporation 82557 [Ethernet Pro 100] (rev 5).
^^^^
IRQ 10.
Master Capable. Latency=64. Min Gnt=8.Max Lat=56.
Prefetchable 32 bit memory at 0xcb7ff000 [0xcb7fffff].
I/O at 0x7c00 [0x7c1f].
Non-prefetchable 32 bit memory at 0xcfe00000 [0xcfefffff].

it is the same chip, this particular interface is 10mbit/half duplex, and
all the interfaces transfer 1G+/day (some small files, some larger than 500 megs)
with no problems, I should note this:

eth0: OEM i82557/i82558 10/100 Ethernet, DE:AD:BA:BE:CA:FE, IRQ 10.
Receiver lock-up bug exists -- enabling work-around.
^^^^^^^^^^^^^^^^^^^^
Board assembly 009542-001, Physical connectors present: RJ45
Primary interface chip i82555 PHY #1.
General self-test: passed.
Serial sub-system self-test: passed.
Internal registers self-test: passed.
ROM checksum self-test: passed (0x24c9f043).
Receiver lock-up workaround activated.

etc etc, for every interface.

I'm up to 2.4.10, it's worked fine on 2.4.2, 2.4.4, 2.4.5-8, and 2.4.10 so far.
(I didn't use the kernels not mentioned)


Good luck.
