Hmm I'm out of ideas.

If the nf_reset patch helps it must be somewhere after
ip_finish_output2(). This could be an arp queue, a device queue
or a packet socket queue. You could add an nf_reset to dev_queue_xmit
and see if it changes anything.

There's no raw table in 2.4, so the wait-for-untracked-refs patch should
go in the 2.4 raw table patch. For 2.6 I'm not sure yet, Pablo has a
patch that changes how untracked works and makes this patch unnecessary.
The nf_reset patch with go in my next 2.4 update, which should happen
soon.
