I'd like to extend this so all devices on this adapter are visible,
perhaps it helps in debugging this case. Note that I also lowered the
tagged queuing depth to the default of 32. This had no effect.:

This stands. I would like to debug this, but a few recommendations of
what to do and where to start would be appreciated.
