This is weird. It looks like something on the netfilter module
initialisation path has called smp_call_function(garbage_address). But I
cannot see where anything like that could happen.

Hmm, this is 2.4. Is this a regression against previous kernels?
I can't see anything to suspect here: we certainly don't use
smp_call_function in the netfilter code. I wonder if loading a
different module causes the same problems.
BTW xor.h declares non-inline functions which I find disturbing. Hmm,
maybe that tricky asm xor stuff blatts something which the
smp_call_function wants to use...?

No, only iptables loaded as modules, all other in kernel.

Maybe. I see to many calls to flush_tlb_all_ipi when iptables start. See
log (i'm add to smp_call_function_interrupt simple printk to see what
function it call)
