This is likely a firmware bug on this device. Contact the card vendor for a firmware update. VPD stands for Vital Product Data, vendor may store product specific information in VPD, such as "serial number" etc. It may depend on some micro-controller on the PCI card to access those data. And VPD is optional, doesn't affect normal PCI functionalities. > > -- > To unsubscribe from this list: send the line "unsubscribe linux-pci" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html >
