That sounds familiar... I had similar trouble with 2.6.20.1 (running UP on a 200 MHz Pentium MMX
machine) when I unloaded the nf_conntrack_h323 kernel module. The messages continued until I
rebooted, although I never saw an oops. I am currently avoiding the problem by *not* unloading any
netfilter modules.

Cheers,
Chris
