Since my original report I moved the new system into a test-box.

I now tried to get a 3Com NIC (3c905c) to work on the PCI-bus. That
doesn't work either. I get those "nobody cared" IRQ-messages.
I also updated the BIOS.
There seems to be something wrong WRT ACPI irq routing.

What further data should I provide to get this solved?
