There were changes in dummynet's configuration functions that, among
other things, dealt with protecting certain code sequences with the
proper SPL. They went into the CVS repository after 4.8. I can't tell
whether these fixes would help in your case but you may want to look at
rev. 22.214.171.124 and 126.96.36.199 (RELENG_4) in any case:
