I really meant can you recreate it with a simple test case without lots 
of rules.

This is the wrong way round - if you didn't get an error prehaps there 
was already a queue on from a previous test - that could confuse things.

I am not sure if it makes a difference but normally the handle would be 
0050: maybe it is clashing with the parent classid without the :

It should be doable - I may have missed something else. I assume you are 
testing with

tc -s qdisc ls dev eth0
tc -s class ls dev eth0
tc -s filter ls dev eth0

not nice with lots of rules - but worth it to check the counters.

I think the list had died again - so make sure you cc me if you reply.
