I have a "big" environ with htb (kernel .26) and it works well, without
problems. Never seen up and down course.

Also here the same.

With that rules, also here :( . Starting to say that I'm not a big tc
expert but after some test, it's seem that tbf create the problems:
if you try to remove that rule, it'll work. Also tried sfq or cbq like last
queuing and seem to shape correctly. (my test was done with scp and iptraf)
Have you tried it?
