Hm, I just did exactly the same thing here. I don't see this.

What do your filters look like?


I do see 
 HTB: dequeue bug (8), report it please !
which I think is because i have too low burst/cburst settings.

My settings currently look like:

tc class add dev $DEV parent 1: classid 1:1   htb rate ${BW}kbit burst 8k cburst 8k
tc class add dev $DEV parent 1:1 classid 1:10 htb rate ${BW80}kbit ceil ${BW}kbit burst 8k cburst 8k prio 1
tc class add dev $DEV parent 1:1 classid 1:20 htb rate ${BW10}kbit ceil ${BW}kbit burst 4k cburst 1k prio 2
tc class add dev $DEV parent 1:1 classid 1:30 htb rate ${BW10}kbit ceil ${BW}kbit burst 2k cburst 1k prio 3

(where ${BWxx} = xx% of the total bandwidth I want on that link)
