This 0x1 event is a receive error. It seems only users with cable modems
have this problem. I've got no idea why it happens with cable modems and
nothing else, but it could indeed be crappy hardware on the modem side.

What we don't know yet is if the receive error is hard or soft. Soft
errors generally can be recovered from, so it would be a shame throwing
the packets away.

Your switch didn't let the malformed/incorrect packets through, so you
computer didn't see them.

Could you please try the attached patch (will create LOTS of debug
messages) for a few minutes and mail the relevant part of your
/var/log/messages to me privately (it will be >100 kB, so I don't want to
burden the list with it).
