>Description:
Fatal double fault
eip = 0x05e1ed0
esp = 0xd400e000
ebp = 0xd400e004
Panic: double fault
The above fault happens when net.inet.ip.fw.one_pass is set to 0 *on boot* of the machine.
Again, *on boot*.
Settings on my firewall here that may be of importance to reproduce the crash:

>How-To-Repeat:
Given the settings above, my machine always crashes during boot. If I comment out the loading of the firewall, it boots normally. After which I can load the firewall by hand with no problems. It's actually a mistake that net.inet.ip.fw.one_pass=0 was set, as it was initally set to test other things. That's not what I wanted, however it still creates a reproducable fault with it set to 0.
Once again, I can only produce this on boot of the machine.
>Fix:
Unknown. I haven't been able *yet* to get a kernel dump, but in the event that I do, I will provide that information here as well.
