And what one did you use for 2.4.16 ?

:) I only need to determine whether the bug is related to
change in htb, pppoe or kernel. If 2.4.16 worked then we need
to minimize code size with the bug. 
Not it seems that you used at least different kernel and htb.
Not sure about pppoe patch (or is it in kernel?).
Try to use htb2_2.4.17.diff with 2.4.16 - it could say whether
the bug is in htb (the diff should work with 2.4.16).

probably not. The value is not used if you attached you own
qdisc. It is only used as default size for default qdisc.
What you might try to do is to use pfifo instead of SFQ and
set pfifo's limit to say 20 packets.
It is not long term solution but could help up to find the
problem. 
The results you sent shows no backlog - probably it is too late
or the problem is elsewhere.
I don't know pppoe - it could be helpful to grep on source and
look when the error message is printed. It could help us to see
what pppoe sees as error.
