    Subject[regression, bisected] Xonar DX invalid PCI I/O range since 977d17bb174
    I got the following bug report:
    | After upgrading kernel from 2.6.32 to 2.6.34-rc4 my Xonar DX stopped
    | working. Kernel log has:
    |
    | [kernel] AV200 0000:09:04.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
    | [kernel] invalid PCI I/O range
    | [kernel] AV200 0000:09:04.0: PCI INT A disabled
    | [kernel] ALSA device list:
    | [kernel] No soundcards found.
    |
    | According to git bisect the culprit is:
    |
    | commit 977d17bb1749517b353874ccdc9b85abc7a58c2a

    | PCI: update bridge resources to get more big ranges in PCI assign unssigned

    Unfortunately, the bug tracker is dead, so I cannot ask for further
    information. (If somebody renews the domain, this report will be at
    <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4982>.)

    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
