That's not a stall, that's selective-ACKing (see the ranges listed on the right of each ACK line).

This could just be a coincidence. But it could be that packet loss is now more likely for some reason. Does the rx_fifo_errors statistic increase quickly with the later version of the driver? (This seems to be the only receive error type reported.)
