------- Comment #11 from [EMAIL PROTECTED] 2008-01-02 07:33 -------
That the ehci module can't work is caused by uncorrect PCI interrupt route.
a. acpi=noirq
IRQ 5 is used for ehci and the ehci module can work well.
b. acpi enable
OSPM will use the pci interrupt route entry defined in ACPI table and LNKC
device is used for ehci and audiopci device. If acpi_irq_balance is used, the
new irq number(11) will be programmed into LNKC because the default IRQ number
is not in the possible IRQ list.
>ACPI: PCI Interrupt Link [LNKC] (IRQs 3 4 6 7 10 11 12) *5
Unfortunately the above setting has no effect because the LNKC device is
hardrouted to IRQ 5,which means that the interrupt route for ehci is uncorrect.
So the ehci can't work well in case of using ACPI PRT table.
The bug will be rejected . (Of course the system can work well if it is booted
with the option of acpi_irq_nobalance).
