Hi all,

I've configured succesfuly different QoS configurations, but there is
one that *allways* returns a segmentation fault in the kernel module (or
code). This part of the kernel seems to crash when installing an IP
filter. I've tried the code in 2 different computers with different
hardware and even different kernel version (2.4.25 and 2.6.4)

The code is the following:
-------START--------
tc qdisc add dev lo root handle 1: tbf rate 250kbit burst 5k limit 5k
tc qdisc add dev lo parent 1: handle 20:  prio
tc qdisc add dev lo parent 20:1 handle 210: sfq perturb 10
tc qdisc add dev lo parent 20:2 handle 220: tbf rate 250kbit burst 5k \
                                                     limit  5k
tc qdisc add dev lo parent 20:3 handle 230: sfq perturb 10

tc filter add dev $ETH_IPSEC protocol ip parent 1:0 prio 1 handle 2 \
                                                 fw flowid 20:3
-------END----------

The line "tc filter..." produces the system crash. Actually, the system
is usable, but any command refering the QoS hangs (tc, iptables...).
Even the system shutdown is not available because Linux freezes when
stopping the network. It seems that is something related to the filter
section in the QoS modules.

In the files attached are described the technical characteristics of the
computers.

Thank you for your work.
Jaume,
