    Subject[IRQ map] VIA C7 CN700 2.6.23-rc9-git USB IRQs disabled
    Booting git snapshot of about 6 hours ago, getting the following:

    USB Universal Host Controller Interface driver v3.0
    ACPI: PCI Interrupt Link [ALKB] enabled at IRQ 21
    ACPI: PCI Interrupt 0000:00:10.0[A] -> Link [ALKB] -> GSI 21 (level, low) -> IRQ 18
    ACPI: PCI interrupt for device 0000:00:10.0 disabled
    uhci_hcd 0000:00:10.0: init 0000:00:10.0 fail, -16
    uhci_hcd: probe of 0000:00:10.0 failed with error -16
    ACPI: PCI Interrupt 0000:00:10.1[A] -> Link [ALKB] -> GSI 21 (level, low) -> IRQ 18
    ACPI: PCI interrupt for device 0000:00:10.1 disabled
    uhci_hcd 0000:00:10.1: init 0000:00:10.1 fail, -16
    uhci_hcd: probe of 0000:00:10.1 failed with error -16
    ACPI: PCI Interrupt 0000:00:10.2[B] -> Link [ALKB] -> GSI 21 (level, low) -> IRQ 18
    ACPI: PCI interrupt for device 0000:00:10.2 disabled
    uhci_hcd 0000:00:10.2: init 0000:00:10.2 fail, -16
    uhci_hcd: probe of 0000:00:10.2 failed with error -16
    ACPI: PCI Interrupt 0000:00:10.3[B] -> Link [ALKB] -> GSI 21 (level, low) -> IRQ 18
    ACPI: PCI interrupt for device 0000:00:10.3 disabled
    uhci_hcd 0000:00:10.3: init 0000:00:10.3 fail, -16
    uhci_hcd: probe of 0000:00:10.3 failed with error -16
    ACPI: PCI Interrupt 0000:00:10.4[C] -> Link [ALKB] -> GSI 21 (level, low) -> IRQ 18
    ACPI: PCI interrupt for device 0000:00:10.4 disabled
    ehci_hcd 0000:00:10.4: init 0000:00:10.4 fail, -16
    ehci_hcd: probe of 0000:00:10.4 failed with error -16

    With "pci=routeirq" it is the same, but then it's "IRQ 17" instead of 18,
    and the line

    ACPI: PCI Interrupt Link [ALKB] enabled at IRQ 21

    is missing. Works with Debian etch default 2.6.18. /proc/interrupts under
    .23-rc9-...:

    $ cat /proc/interrupts
    CPU0
    0: 31756 IO-APIC-edge timer
    1: 2 IO-APIC-edge i8042
    8: 1 IO-APIC-edge rtc
    9: 0 IO-APIC-fasteoi acpi
    12: 4 IO-APIC-edge i8042
    16: 2627 IO-APIC-fasteoi sata_via
    19: 472 IO-APIC-fasteoi eth0

    Under 2.6.18:

    ACPI: PCI Interrupt Link [ALKB] enabled at IRQ 21
    ACPI: PCI Interrupt 0000:00:10.0[A] -> Link [ALKB] -> GSI 21 (level, low) -> IRQ 177
    PCI: VIA IRQ fixup for 0000:00:10.0, from 10 to 1
    uhci_hcd 0000:00:10.0: UHCI Host Controller
    uhci_hcd 0000:00:10.0: new USB bus registered, assigned bus number 1
    uhci_hcd 0000:00:10.0: irq 177, io base 0x0000f900

    Thanks
