The sum up is that AMD claims it's not a bug with the Athlon processor, but with the motherboard. More detailed information can be found on this LKML post." An Anonymous Coward points to a similar explanation at Linux Weekly News. Update: 01/25 01:25 GMT by T : Daniel Robbins from Gentoo clarifies: "AMD is not calling this a 'motherboard' issue, it is an interaction between a feature of the Athlon called 'speculative writes' and the design of the GART, which is not cache-coherent. It's a 'Athlon/cache coherency/GART' problem, not a 'motherboard' problem."
