    SubjectRe: AMD 8131 MSI quirk called too late, bus_flags not inherited ?

    Worked here on a PCI-X AMD-8131 based system.

    ----

    Offtopic, something I wanted to bring up with respect to MSI,
    but never had the time to debug:

    If I do

    pci_enable_msix, pci_disable_msix

    then later

    pci_enable_msi

    on the same device fails with the following message:
    PCI: 0000:08:00.0: Can't enable MSI. Device already has MSI-X vectors assigned

    This is not something new - has been happening since forever.
    Looks like not all MSI-X vectors get properly unassigned by pci_disable_msix.

    One way to test this is by loading mthca driver with msi_x=1, unloading
    and loading with msi=1.

    Someone has any idea what's wrong?
