please accept my excuse for this posting. I didn't intend to critizise
your firewall code which works as you say. The problem I've mentioned
seem to be related to the packet logging feature (CONFIG_IP_FIREWALL_VERBOSE)
of the firewall. When I flood ping an address for which packets will
be logged via syslog the machine crashes. And you won't call the
packet logging via printk & syslog hyper optimized, don't you?
