Created attachment 757279 [details] Photo of the kernel panic trace Description of problem: The kernel on the router machine (running F18) panics when one of the clients in my network runs the Netalyzer (http://netalyzr.icsi.berkeley.edu/) test. Set up is as follows: kernel-3.9.4-200.fc18.x86_64 iptables-1.4.16.2-5.fc18.x86_64 shorewall6-4.5.16.1-1.fc18.noarch The machine is connected via ADSL PPPoE to the Internet. A SiXXS Tunnel with static endpoint is being used for IPv6 connectivity. The system uses shorewall/shorewall6 for the firewall. The network card is a IBM dual-port e1000e.
This issue seems to be netfilter related. It only appears when shorewall6 is started. It happens during the step "Checking the network's MTU for IPv6" in Netalyzr.
can you post the backtrace please?
Sorry, I missed the backtrace photo. Looking at it I think its a dup of 892060. I'm closing this as a dup of that. If the problem recurs on the latest kernel, please reopen this. Thanks! *** This bug has been marked as a duplicate of bug 892060 ***
