If the hardware cannot handle them, it's a hardware bug. If the hardware does handle them correctly but the software doesn't, that is a bug in the bridge driver. We have a couple of host bridge drivers that register a trap handler and then look at the bridge registers to determine the exact cause. Which host bridge driver do you use? Arnd
