%CABLE_MODEM_HWIC-3-CONTROL_PLANE_FAIL: RBCP failure : Adding service flow ACE failed - Ethernet type not supported

I'm having the same issue as this guy: https://supportforums.cisco.com/message/2017814#2017814

but the responses in that thread are not enough to fix the problem- or even get through tier 2 support at the ISP.

This happens every few hours. It requires a cold reload of the router to repair- there might be another way to updown the interface only that works but not one that I'm aware of. I know this is a strange issue but any answers or ideas on how to diagnose would be great as it is a huge detriment to services. It would be nice if we had more than one choice of cable internet provider in this area.

Here is the sh ver:

This also randomly happens:
