I can see this is going nowhere. The information below is essentially
just what you already posted, and I'm sorry, but it's not enough for
me to fix anything. Can you tell me the model and BIOS version? Maybe
I can find another one somewhere and do my own poking around.

What I'd like to know is (a) what Windows reports as PCI bus resources,
and (b) what the Linux dmesg looks like with the patch here:
https://bugzilla.kernel.org/show_bug.cgi?id=15533#c5
CONFIG_ACPI_DEBUG=y and the arguments "acpi.debug_level=0x00010000
acpi.debug_layer=0x00000100".
