   Paul,
 
   I have several questions, to narrow scope of problem search.
 
 1) Is there active traffic flow when machine reboots?
 
 2) Is the problem reproducible if you remove all 'queue' rules
    from rc.firewall?
  If the answer is 'no', can you pls add these rules one by one
  and try to reproduce the problem. I mean first try only rule 1000,
  then 1000 and 1100, etc..
 
 3) Can you try to reproduce the problem with this patch. This is
 not a fix, but it will give some idea on what's going on.
 
 Patch (TABS are lost, apply it by hand):
