HP Procurve Cisco Uplink - Large amounts of FCS errors

I'm having a ton of trouble with this. I have a site that is has HP Procurve switches and a Cisco router.  

I'm seeing about 10% of all frames show as FCS Error Rx.  My port stats are showing around a 5% link utilization.  

Originally the links were not properly auto-negotiating (switch was trying 1GB, where the Cisco is 100mb).  I hard set the switch port to 100mb, cleared my stats and watched.  Still hitting about 10% FCS Rx Errors.

I'm having someone onsite replace the patch cable.  Outside of that, I am at a loss of what to do next.

I wonder if one side is auto and other side is hard-set FullDuplex, resulting in a Half vs. Full situation.
Should be either Full-Full or auto-auto.

Hmmm, both sides are now showing 100Fdx.. although the cisco is on auto HP is hard set
