Warning indicate that PCI bus disconnected device. I'm not sure how this can happen, perhaps this is firmware bug or PCI kernel subsystem problem. Eventually this could be a pure hardware problem. Is this issue reproducible for you ? If so, we could run with some debugging prints to investigate problem further. Otherwise, I do not see much chance to fix this issue.
