Unfortunately, I don't know why your firmware would be saying that. We could add some more debug printks to see what firmware thinks about your system... Or we could just wait and see what happens after you get your hardware replaced. > I have a card in one of the slots only this time. > > > Also, quick dummy check, you are trying to power on populated > > slots, right? :) > > Yes :-) > > > Can you send the output of lspci -vv?

If you want to poke us again after your hardware swap, please do so.
