If there is no card connected, why would the bridge observe a fatal
error?
fatal error could be coming from anywhere let us say below RootPort..
and RP observes it and decides to take the tree down....
Is that the case Keith is talking about ?
Why will re-enumeration be a problem even if runtime PM is active ?
I assume that enumeration will get bridge out of D3.
