Hi Karsten, about the complete power cycle issue: While testing I had same problem like you... I had to remove power cord to get my server back... Now I tried a soft "reboot" and I get any issue.. So my patch seems to be fully working and I'd like to know how to commit into mainstream. I think may be useful for other pc based on same chipset like ours.
