Vecima Tuning Adapter constantly rebooting Tivo Roamio

I finally was able to get the new Vecima tuning adapter working with my TiVo Roamio after about 2 weeks of back and forth with cable card tech service and finally started receiving all the channels I should be. However, now my Roamio is repeatedly rebooting at random when it receives some commands like rewind etc. Once it reboots, it doesn't see the tuning adapter.  I then have to power cycle to TA and power cylce the Roamio again to get everything working. This has happened several times and is very frustrating. The TA appears to have the 1.8.0 firmware. Any suggestions on troubleshooting would be greatly appreciated.
