--- Comment #11 from Michael Meiszl <michael at meiszl.de> ---
Update: started manually, the machine ran for 24hrs like a charm!

maybe somebody else should try this simple trick (set firewall to NO in
rc.conf, reboot, login in and do "service ipfw onestart") and check if it works
for him too?

This morning, I was curious and thought, maybe I could get the same effect if I
delay the firewall loading at boot time by editing the /etc/rc.d/ipwf file. I
have tried "Required: LOGIN" and rebootet.
Sadly, it did not work, the machine crashed after 2mins again :-(

Turning it off and started it manually like described above worked once more,
it is up and running for over an hour now already (and I dont expect it to
crash anymore).
But of course, this is not really an option. Usually the box runs forever
unless a major update comes in and brings a new kernel. Then it reboots
automatically and I now always have to remember to start the firewall
afterwards by hand.

I have supplied the latest kernel crash listing here as an attachment, maybe
somebody can take a look at it and find out what is happening? I have some more
boxes to update but I wont start unless this bug is fixed.
