There is no CPU load. For the record, I encountered the same issues some time ago. I couldn't get a SiI 3124 based PCI-E card to work on an IIRC NVIDIA based (AMD) motherboard: I encountered the "softreset failed" messages. I had a friend try the card on another system, and this time it reportedly detected the drives successfully but the performance was bad. > I assume this is a problem with the PCIe bridge.
