Yes, it's leaf class. I recomiled my kernel and they are again negative.

Maybe it's something about my kernel? I did some patching:

kernel 2.4.22 + grsecurity 1.9.12 + patch-o-matic 20030912 (quite lot's
of patches) with htb20030625 patch + imq for 2.4.21 + imqnat + layer7
0.4.1a

iproute2 with layer7 + htb overhead patch

iptables 1.2.9 + grsecurity 1.2.9 + layer 0.2 + patch-o-matic 20030912
with htb20030625 patch
