Of course, this wreaks real havoc on NFS and productivity in > general. > > The tx underrun occurs with various amounts of data queued or ready > to be queued to the card. There is no one set amount of data. > > Yes, I know, I could try -current and the "combined" if_dc driver, but > I just don't have the time to do frob -current.
