Cisco Router/Switch: "%MV64340_ETHERNET-5-LATECOLLISION: GigabitEthernetX/X, late collision error"

Have you seen this on the console?
"%MV64340_ETHERNET-5-LATECOLLISION: GigabitEthernetX/X, late collision error"

Turns out its a speed/duplex mismatch issue.  This issue was slow internet and I found out that the ISP changed their side without letting my customer know.  Just not cool, so I changed my customer switch side so that they could get their full speed back.  ISPs can be a little frustrating.  Reminds me of Brad's post here.
