reproducible panic on 188.8.131.52

First let me say thank-you for netfilter; I have lost count of the
number of firewalls I've built with it. Excellent software!
Now onto the problem...
I just built linux 184.108.40.206 and am now having a very reproducible
kernel panic. After running my firewall script which should enable
simple masquerading from one interface to another, the machine will
panic as soon as it receives a packet which would be REJECTed. For
instance, under my current configuration, ICMP packets sent to the
router's IP from a machine on the LAN match the default REJECT policy,
and will trigger the panic every time. Also, under this kernel, the
masquerading doesn't work; packets are forwarded out to the net, but
the replies never make it back out to the LAN (ie maybe connection
tracking isn't working?). Even stranger, masquerading *did* work
momentarily when I first tried it (before the first panic) but hasn't
worked at all (under this kernel) since then. And if I flush the
tables, nothing I do will make it panic, but when I reload the rules
it will panic as soon as it tries to REJECT something.
Everything seems to work perfectly fine under my other kernel
I don't know how to get the full text of the kernel panic (how do I do
that btw?), but I copied down the end of it:
Code: 0f 0b 5f 5b 00 80 7f 44 c0 83 c4 14 5b c3 90 8d b4 26 00 00 00
Kernel panic: fatal exception in interrupt
In interrupt handler - not syncing
Thanks for any help!
