Hi, Zbignew
    From the info in comment #10 it seems that the interrupt pin of OHCI is
routed to 20/22 of I/O APIC on windows.
    But from the info in comment #6 it seems that sometimes the interrupt pin
of OHCI is routed to 21/22 of I/O APIC. Sometimes it is routed to 20/22 of I/O
APIC.

    When the boot option of "noapic" or "acpi=noirq" is added, it will use the
I8259 instead of I/O APIC. 
    But it is strange that the OHCI can work well if the I8259 is used. But it
can't work well under the I/O APIC mode.

    And from the acpidump it seems that still link device is used even when it
works in I/O APIC mode. I don't know whether this is related with the
BIOS/hardware.

thanks.
