If not, I'd think HW > as well. Yes, actually of the 6 cards I have, all are seen except the USB card. And the USB card is seen in all other slots. So it appears to be a SLOT issue, but not a card issue. Somehow this card is unique and uncovering an error that I don't know about yet. Perhaps I have a single address line sizzled or something. This is the same slot that has the IO resource allocation problems; I don't think I need to debug that in Linux. OR.. Is there any PCI test code out there??? Maybe I should forego the drivers, and figure out some kind of test. I made a blind assumption in U-boot that if it worked to detect cards that everything was in order. > > > All the cards that are seen by U-boot have the IO resource problem. > > Only > > when in Slot 3. > > > > I probably need to direct this at the U-boot crowd, but what about > > these > > defines in U-boot?
