Receiving ICMP6 Checksum Errors

[george+6bone@m5p.com]

I'm getting sporadic log entries informing me that I'm receiving ICMP6
checksum errors from 3ffe:3200:0001:0006::0001.  I used whois to get the
name of a responsible person and I sent him email, but there has been no
response.  Is this happening to anyone else?  It's hard to believe that
there's anything nefarious going on, but I'm curious, at the least,
whose kernel (or application using raw sockets, I guess) is sending out
these malformed packets.                             -- George Mitchell
