------- Comment #102 from [EMAIL PROTECTED] 2007-10-28 18:51 -------
Thanks for the info.
>From the comment #95 and #98, it seems that the workaround patch can fix the
following issue and configure the interrupt of PCI device using ALKD Link
device correctly.
ACPI Error (uteval-0275): Type returned from _CRS was incorrect: Integer,
expected Btypes: 4 [20060707]
[ 3.896000] ACPI Exception (pci_link-0278): AE_TYPE, Evaluating _CRS
[20060707]
[ 3.896000] ACPI: Unable to set IRQ for PCI Interrupt Link [ALKD]. Try
pci=noacpi or acpi=off
[ 3.896000] ACPI: Invalid IRQ link routing entry
[ 3.896000] ACPI: Unable to derive IRQ for device 0000:00:10.3
The above error message is caused by the error _CRS method definition in ALKD
device.
Method (_CRS, 0, NotSerialized)
{
Return (0x00)
}
The BIOS has another problem that _SRS method is uncorrectly defined in the
ALKA, ALKB, ALKC, ALKD.
Method (_SRS, 1, NotSerialized)
{
}
And the following error message is related with the above error.
ACPI: PCI Interrupt Link [ALKA] disabled and referenced, BIOS bug
ACPI: PCI Interrupt Link [ALKA] BIOS reported IRQ 0, using IRQ 20
ACPI: PCI Interrupt Link [ALKA] enabled at IRQ 20
ACPI: PCI Interrupt Link [ALKB] BIOS reported IRQ 11, using IRQ 23
ACPI: PCI Interrupt Link [ALKB] enabled at IRQ 23
ACPI: PCI Interrupt Link [ALKC] disabled and referenced, BIOS bug
ACPI: PCI Interrupt Link [ALKC] BIOS reported IRQ 5, using IRQ 22
ACPI: PCI Interrupt Link [ALKC] enabled at IRQ 22
