I am now hearing similar things with respect to power supply issues. Is it possible that the larger power supply is providing cleaner power which is improving the situation. While I have not checked the actual power usage requirements of the BP6 with it running two CPUs at 100MHz FSB, I have a difficult time believing that (A) the combination needs more than a 250W power supply in the average machine, and (B) an increase of a mere 50W improves the situation.
Unfortunately, I am not an expert on motherboard design, nor on SMP in general. I do not have the facilities to test or confirm any of these findings. I have left that to others, but it appears they're a rare breed. It sure would be nice if ABit could do something to help us out and answer some questions.
All I know is that I started to worry when I first noticed these APIC error messages in the log in 2.3.18 (or thereabouts).
