Before I started using Netfilter, I never had problems with a cipe I ported
to 2.3.x (the version I am currently running only modifies struct device to
struct net_device. I had a more thorough port at home, but I used this
version for a long time with no problems as well). I tend to use most of my
memory and so I would think any scratch padding would be obvious.

After a while, any cipe traffic will cause X to crash. Alt-sysrq-r and then
alt-f2 (my standard start terminal), then startx and I am back... but it
will crash almost immediately.

At this point I can kill ciped-cb but cannot rmmod cipcb.

Any suggestions, helps, or pointers to even an experimental replacement for
cipe would be great. (I do not want to screw around with FreeSwan... I also
need it to use ONE UDP port of my choice, since I cannot modify my firewall
remotely.)
