[LARTC] tc -s class problem (with cbq only)

[<arek@chelmnet.pl>]

I have changed kernel to 2.2.22 and have a problem:

#tc -s class ls dev eth3
and
#tc show class dev eth3
and
#tc -s -d class ls dev eth3

shows me NOTHING when i use CBQ queues on interface !!!

i can olny watch queues (QDISC) with:
#tc -s qdisc ls dev eth3
(this is working OK, as earlier)

I tried many of tc bin's (from devik, compiled, old , etc) - nothing help.

the tc -s class ls dev eth0 works fine, when i used HTB queues.

How to solve that problem ?

this is trace of problem:
