I don't know where to go with this.  We do have some _PRT quirks in
drivers/acpi/pci_irq.c, but since Windows 7 works fine without any
quirks, adding a quirk to Linux doesn't seem like the "right" fix.

Lubos, would it be possible for you to collect a Windows system report
using AIDA64?  I think there's a free trial version here:

Maybe somebody can compare what Windows does with what Linux does and
figure out the difference.
