In my experience testing around here, I've seen Athlons with AMD 750 chipsets run Linux reasonably well even before the Athlon and 750 were released to the public. Newer VIA chipsets, howeverand especially the ATA disk controllershave stumbled badly in Linux, even with Pentium III processors. I even mentioned it a while back, and we got some answers, but no definitive remedies.
What do you guys think? Is it only Athlons, or is it just a Via chipset problem, or what?
