Can you post the output of "show eobc"?

eobc is the ethernet out-of-band connector and is the main control plane 
communication mechanism between the sup and the line cards.  If you're 
seeing errors on the link, then this probably means that there's a 
physical problem somewhere on the backplane.

Try: "show platform eobc all"

or:

# remote command module <number> show interface <intname>

I can't remember whether you can examine the EOBC using "remote command" 
- it's been a long time since I've logged into a 6500/7600.
