That might explain things, although it shouldn't have worked before

CBQ creates default pfifo qdiscs for its leaves, these use a limit
of txqueuelen or 1 if it is zero. So even small bursts will cause
drops. Do things improve if you set txqueuelen to a larger value
*before* configuring the qdiscs?

Another thing is that CBQ on bond will probably not work properly
at all, it needs a real device since it measures the timing between
dequeue events for idle time estimation. On software devices this
doesn't work.
