--TB36FDmn/VVEgNH/ Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Can someone please look into this ipv6 panic? It is now my #1 panic on 6.0 (every few days, and I hardly make any use of ipv6 except for light nfs and tcp traffic), so it would be good to get it fixed before the release.
