Probably "symmetric multi-processor", a kernel enabled for multiple 
CPU's. It could be that you have found a Fedora bug.

If badhost only has one CPU it's wasteful to have SMP support, but as 
implied above, it could be a kernel configuration bug relating to the 
non-SMP kernel.

I'm sticking to my guess. The rules which did not load (if I read it 
correctly from the diff) all used --protocol extensions.

I know little of netfilter / iptables internals. I don't know where 
those extensions load from ... [WHAM] ouch, I was just hit by an 
inspiration.

Firewall loads before mount -a; probably at that point only the root 
filesystem is mounted. If the match extensions are on /usr, we can't 
get to them. I bet badhost has a separate /usr partition and goodhost 
has /usr on the rootfs.

If so, yes, this is an OS bug. And don't just write set to a file, do 
"mount > /root/firewall-mounted-fs" too. (I hope /root isn't a symlink 
or otherwise on a different FS.)
