I haven't seen the problem after 7 days uptime with
2.6.26
With 2.6.25.x was very rare. My boxes are ipsec gateways
driven by openswan, squid and netfilter.
Network driver is 3c59x were the problem happened.

I was getting the warning both on system with and
without sfq/htb

On boxes without ipsec/netfilter (sendmail server)
I did never get this message.

Same for me. I do policy routing based on fwmark.
Just to be clear: I get this message with ipsec/
netfilter/policy routing and with/without sfq/htb
