 I spoke too soon. The panics and corruption are gone, but there's still the=
  problem of local ipv6 addresses being used 'as' ipv4 addresses which resul=
 ts in bad source addresses:
 
 Jun 30 10:50:42 adinava kernel: ipfw: 65529 Accept TCP 1.23.2.0:28593 <some=
  ext. IP>:25 out via bce0
 
 I'm having tons of those, where 1.23.2.0 is obviously not a locally bound I=
 P but the result of the local system trying to send a SYN from a local ipv6=
  address to a remote ipv4 address.
 
 PS: Excuse me for signing my previous followup.
