Yes, it was the latest BIOS for this board, but Intel put a new to the
Internet these days. I updated the Bios, but no change at all.
There is only one ACPI-Relevant switch in the Bios, so I don´t think
that the Bios configuration is the problem. The only on ACPI-relevant
option is:
"Resume from S5 by LAN". But I don´t belive that this makes the problem
(and I tryed both: on and off). There is no way to modify/reservate
interrups in the Bios.

It looks like very buggy ACPI-tables in the Bios.
