Luis,

I saw now a message:
 hotplug reports a wrong irq. Working around

and I found a new part in the code which reassigns the irq under
certain conditions. I commented this out and it works again.

If you want to know what is strange in my system, please ask some
detailed questions. I do not know much about ACPI and such.
