Without netfilter at all? Well, without netfilter I can't get it to crash. The problem is without netfilter I can't actually use it the way I use it to get it to crash. I rebooted into a netfilter kernel, and did all the steps I'd used on the no-netfilter kernel and it ticked along happily. So the result of the experiment is inconclusive. Having said that, the backtraces certainly smell networky. To get it to crash, I have to start IE in the VM and https to the public address of the machine, which is then redirected by netfilter back into another of the VM's. I can https directly to the other VM's address, but that does not cause it to crash, however without netfilter loaded I can't bounce off the public IP. It's all rather confusing really. What next Sherlock?
