It's definately not a problem with the physical port. I've actually tried
both... both work well under MacOS. The AAUI works slightly better under
Linux, but is still useless.
From what I can tell, the problem I'm having is pretty much related to the
problems had by 7200 owners trying to use the on-board Ethernet. (Makes
sense, the PowerCenter is the same architecture.) From what I have gathered
on the net, it's some sort of breakage in the Mace driver, possibly
introduced in an early 2.2.x kernel. It may have something to do with
sending long packets, may have something to do with the fact that a hub is
involved, and may have something to do with the early revision of the Mace
chip (9.64) or with how the Ethernet timing is generated (not sure if the
PowerCenter using an ASIC or a separate clock chip).
So far, if someone has the answer to fix it, they are being very quiet about
it. Most everyone seems more concerned with how to install a PCI Ethernet
card.
Does LinuxPPC support USB Ethernet nics?

my Powercenter Pro 180 has both a 10baseT connector and a little apple AUI ethernet adapter. I started having problems with the 10baseT plug (i think it got fried somehow) but popped on an AUI adapter and it works fine. If you have one lying around and/or can borrow one, you might try that.
