They are and aren't the same architecture. As I understand it, the
PowerCenter is a Catalyst architecture while the PowerCenter Pro is a
Catalyst+. The latter incorporating the ATI video and some enhancements to
allow a rated 60mhz bus.
Actually, though, I'm starting to think the problem is not the Mace, but
something more fundamental. (See folowon message)

>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). i *believe* i was running a kernel version of either 2.2.7, 2.2.8, or 2.2.12 and I didn't have any noticable network problems on the PowerCenterPro 180 (prior to a harddrive crash that I haven't had the time to sort out since), but I'm not sure that the PC Pro is the same architecture, so I'm not sure that that gives you any useful info.
