Try using a SPAN of the CPU to see what traffic is hitting the CPU; this
is by far the quickest way to find the cause.

Port 80 traffic to where? Can you show some?
There must be something wrong with the traffic or your config for the
7600 to be process switching it. You need to

Sounds like your router is punting all traffic. Are you seeing the
following errors in your logs?
%CFIB-SP-7-CFIB_EXCEPTION : FIB TCAM exception, Some entries
TCP Adjust-mss causes the 6k to punt the SYN to SW. I'm not sure if this
will be process switched or CEF switched (interrupt), but I don't see a
reason why we couldn't do it in software CEF.

Ah, well spotted; I didn't see that.
FWIW I have used adjust-mss
