Hi, All
The following error message can be found in the dmesg of bug8896.
ACPI Error (uteval-0269): Return object type is incorrect
[\_SB_.PCI0.ALKD._CRS] (Node da4b49f0), AE_TYPE
ACPI Error (uteval-0275): Type returned from _CRS was incorrect:
Integer, expected Btypes: 4 [20060707]
ACPI Exception (pci_link-0278): AE_TYPE, Evaluating _CRS [20060707]
And the above error message is related to the following BIOS Bug.
Method (_CRS, 0, NotSerialized)
{
Return (0x00)
}
Can we ignore the error about the _CRS method of LINK device and select
IRQ from the possible IRQ list returned by _PRS method?
Thanks.
