Could it just be a particular BIOS setting affecting things as well ? I didnt look at the issue too closely, but on the SMP box below, I was having inital problems until I re assigned the IRQs to be on more sane values if I recall correctly (e.g not 9/11 or shared with something else). I believe I also looked at some DMA settings in the BIOS, but it has been a while since I set this particular box up. On the box below, the IRQ values displayed in the dmesg, are not the same as what is displayed at boot up time. With it, I did get a few fxp time outs and such and the box did panic once. It could be something totally unrelated, but this discussion does ring a bell with me.
