It seems that the kernel does not allocate resources to the modem
controller.  I think it's not the driver's problem.

I don't know what to do in this situation...  but if available, try to
set the BIOS parameter such as "PnP OS" to "No".


The following is the result of my -current PC (for reference).

And I'm not familiar with ACPI, the following is a part of dmesg with
verbose logging.
