Is the port interrupt-driven, or polling, on your system, Andreas?
Here on my system it says also polling, like on Andreas system. What is the difference between interrupt driven and polling?
Interrupt driven means the port has an interrupt assigned to it, and that communication over the port is event based.
Polling means there is a timer running in the kernel which will check the port for activity every few milliseconds or something.
On vendor bios it is interrupt-driven. Is an ACPI part missing to get it interrupt driven?
I think so, yes.
I think this should be easy to fix if it is really acpi related, just a few lines in the dsdt.asl should do the job.
But right now I'm a little bit in a hurry, and maybe I'll find time to do that on sunday or even tomorrow.
