[Openswan Users] Kernel Oops when using htb

[Oliver Schulze L.]

Hi,
I have been using openswan for a few months now.

I recently wanted to limit the traffic and started using HTB.

Then, after configuring HTB and running ifconfig (or snmpwalk),
the kernel crashes with this messages:

Mar  2 17:47:07 myserver snmpd[26618]: Received SNMP packet(s) from

I think there is a problem when using: openswan + kernel from atrpms + 
htb + ifconfig

Here is my info:
openswan 2.4.0
kernel-2.4.20-43_41.rh9.at.i386.rpm
RedHat Linux 9

How can I solve this? Anyone have seen this problem using htb + openswan 
in kernel 2.4

Many Thanks
Oliver
