(If somebody renews the domain, this report will be at .) The Xonar DX is a PCI chip with a 256-byte I/O range behind a PCI-E/PCI bridge. The driver code that caught this looks as follows: err = pci_enable_device(pci); ... err = pci_request_regions(pci, DRIVER); ... if (!(pci_resource_flags(pci, 0) & IORESOURCE_IO) || pci_resource_len(pci, 0) < OXYGEN_IO_SIZE) { snd_printk(KERN_ERR "invalid PCI I/O range\n"); Regards, Clemens -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
