While it's not specific to AMD processors, it happens there more often. I also suspect that this is more likely to be a motherboard issue (possibly BIOS) than the processor itself. The answer seems to be to disable APM. Apart from that, I can only confirm other reports. I'm running 4 AMD processors on my most-used machines, and I don't have any problems.
