  Connection is 256kbit/2mbit, but the down interface is used for SMB also 
  so its shaped from 100mbits. The interfaces are both ethernet.

  Number of rules in Iptables is around 300, and I have a new kernel (from 
  kernel org) and new iptables.

  Number of qdisc/class per interface is 7-8. Leaf classes are SFQ.

  I tryed:
  - running only one part of QOS (down or up) 
  - puting only minimal set of rules in iptables
  - getting kernels from fedora/kernel.org
  - reinstalling fedora.
  - changing clock from standart to gettimeofday
  - changed leaves from SFQ to PRIO
  - changed speeds of QOS.
  - played with my outside interface from HALF to FULL duplex and reverse 
  way.
  and still I had this stalls on the interface which has HTB QoS 
  setup.

  Load of my internet connection is around 10%. Propably you're thinking 
  that I set up my connections parameters too high in QOS, but that is not the 
  case (I think ;-) since I did a little bit of testing and found out the 
  setting which alowed me to keep LAN pings through my internet connection even 
  under heavy load. 

  CBQ works without any problems. 

  Computer is 233 MMX with 128 of RAM (36 MB used for system), NIC's are 
  3com's 905B and 905C. I dont remember if I tryed changing them 
  :-)

  And I dont really now what is that I screw up :-) Wonna see my qos 
  scripts? :D

What sort of load, number of rules/classes and bandwidth do you 
    have?

Andy.
