I'm sorry to report that this still fails for me.  I checked out the
latest CVS, rebuilt netfilter, installed it, rebooted, and tried the
above test case.  It hung the system.  I couldn't use SYSRQ to kill
the offending task either.  Eventually it complained about something
like this:

wait_on_bh: CPU 1
irq: 0 [0 0]
bh: 1 [4 0]

<[c010dqe4]> <[c.....]> <[c.....]> <[c.....]>

I didn't write down the above hexadecimal numbers but if you want
me to research the addresses further, I can.
